An increase from 200 to W in IM KaNO 3 / im KM canams a sharp increase of the nitrate yield: from - 3.0 to - 6.5 eqIv./100ev. The increase in yield reaches its limit value at 800 and equals about 8 equiv./100ev. The sensitizing effpct of glycerin is apparent only vhen its concen- traVion is - 5 .10" M and remains constant for concentrations up to 10-'M. The presence of molecular oxygen (air) inhibits this effect. There are 5 figures and 10 references, of vh1ch 6 are Soviet and 4 RnOish.

TITLE: The Action of I-Radiation on the Aqueous Solutions of Ammonia and Sodium Nitrate (Deystviye y-izlucheniya na vodnyye rastvory ammiaka i nitrata natriya) PERIODICAL: Zhurnal fizicheskoy khimii, 1958, Vol 32, Nr 7, pp 1686 - 1687 (USSR) ABSTRACT: The investigations carried out by Rigg, Scholes and Weiss (Ref 1) showed that in an x-ray irradiation of aqueous ammonia solution saturated with oxygen an oxidation of the NH 3 takes place; no hydrazine or hydroxylamine formation was found, for which reason a direct participation of oxygen in the reaction was assumed. In the present paper this oxidation mechanism is investigated with nitra e ion and molecular oxygen having been g used as acceptor and Co o as y-source. The solutions were saturated with oxygen or an inert gas, and the method of irradiation as well as the method of analysis were carried out as already described. From the experimental results obtained Card 1/3 the authors concluded that the molecular oxygen in the solution The Action of I-Radiation on the Aqueous Solutions SOV/76-32-7-41/45 of Ammonia and Sodium Nitrate does not take part directly in the oxidation of ammonia, but that it only ~GeRSMWS .- the reaction as acceptor of the H-atoms, similar to the nitrate ion. The influence exerted by the oxygen on the yield of NO- observed in the case of 2 high pH values is explained by its inhibiting effect on the reduction of the nitrate ion. The reducing component of the water radiolysis in the oxidation of ammonia in the presence of nitrate ions is represented according to the equation 9H+4,5NO3 - 4,5NO 2 + 495H2O. Finally the authors thank M.A. Proskurnin. There are 1 figure and 3 references, 2 of which are Soviet.

In the case of laoking-*%Mn (the solution is saturated with nitrogen)) the nitrite yield within the range of dose rates of 0-5 - 1000 r/seo is considerably greater (r%j8 equivalents/100 ev). With an oxygen content of 2-5~ in an oxygen-nitrogen mixture above the solution, G N02 is directly proportional to the logarithm of the dose rate. These results Card 1/4 are an indirect confirmation of the hypothe8is on the congruence On the Character and the Role of Intermediate Products SOY/2o-124-6-27/55 in the Radiolytio Reduction of a Nitrate of the disproportionation of the ion of nitric acid and its oxidation to a nitrate-ion by oxygen* For the purpoze of ex- plaining the influence exercised by intermediate,products on the reduction of nitrate several 'exporize7its were carried out concerning the irradiation of solutions-at different temperatures. A temperature variation (within the-tomprerature interval of 20 - 900) apparently exercises only li-t-tle influenoe on the formation of the final products NO and NO-,according to the 5 2 disproportionation reactions (G 8-8-5 equivalents/100ev). N02 Irradiation of the solutions at low temperatures (down to -250) reduces ONO tov 2.5 equivalents/100 evo In the case of a 2 further reduction of the temperature-of-the-solution down to the temperature of liquid nitrogen G NO remiLins practically 2 constant. In oxygenous solutions (whtch--are saturated with air) decrease of the yield begins at high-temperatures and is also due to the interaotion between 0 2and the intermediate products Card 2/4 of the reduction of the nitrate. By applying param gnetic On the Character and the Role of Intermediate Products 9OV/20-124-6-27/55 in the Radiolytic Reduction of a Nitrate electron resonance to the system nitrate-water during irradiation with accelerated electrons it was possible to detect several radicals as intermediate products of ni-trate reduction and also atomic hydrogen at temperatures of from -196 to -700. As so'on as irradiation is stopped. these intermediate-produots vanish quickly, i.e. they vanish all the more rapidly the higher the temperature of the solidified solution becomes. From the above the following conclusions may be drawnsl-) The main,processes of the reduction of nitrate in the solidified-solutions occur before thawing. besides the direct actian of T-radiation upon NO- a reduction of the nitrate by radicals occurs in the solidified 3 solutions~ Finally~ the authors suggest a closer investigation of the properties of the intermediate products of the system by the method of paramagnetic resonance.

The characteristics of the epee- tra of radicals I - IV are given in table 1. Radical I is iden- tified as NO 2, radical II as the ion HNO 30 Radical III was ob- served in acid medius, radical IV in alkaline medium only. These two radicals are called nitrogen-free peroxide radicals, but they have not yet been clearly identified.

TITLE: Problem of radiation chemistry of aqueous solutions PERIODICAL: Uspekhi khimii, v. 30, no, 5, 1961, 645-678 TEXT: The author gives a survey of the development of radiation chemistry of aqueous solutions. He analyzes modern conceptions of the mechanism of radiolytic conversion and tries to give a uniform definition of radiolytic reactions. During more than 50 years, neither a uniform radiolysis theory of aqueous solutions could be developed, nor could the experimental data be explained. The radiation effect upon aqueous solutions is to be taken into consideration, because their radiolysis is similar to that of biologi- cal systems. The production of chemical dosimeters being both, "air- equivalent" and "tissue-like" is of importance. In chapter 1, the con- ceptions having been developed since 1901, are treated. ChApter 2 is devoted to the radical intermediates of water radiolysis. A. OH radicals as oxidative components of radiolysis. Since the OH radicals possess a Card 1/6 22W S/074/61/030/005/001/001 Problem of radiation chemistry... B103/B226 high affinity to the electron, they may appear as oxidizers. In this way, the radiolytic oxidation of halogen ions and many other inorganic and organic compounds is explained. Compared to strong oxidizers, the OH radical may show reducing properties due to formation and decomposition of intermediates of the peroxide type. B. Part played by H atoms in radio- lytic reactionst There are reasons for the assumption that in hydrated state, the H-radical occurs as H30. The present experimental data are in- sufficient for the hypothetical reaction: OH + H2 = H20 + H + 11.6 kcal/mole (7) or OH + CO = CO2 + H + 21.2 kcal/mole (15). The nature of the inter- mediates has as yet not been explained. C. The role of H02 radicals. The HO2radical cannot beidentified by direct observation methods. It- can either be dissociated in 02 and H+ or converted to H202 and 02 by recom- bination. According to the pH value of the medium, R 202 may appear as an oxidizer or as a reducing agent. With an increasing pH value, the reducing effect of the HO2 radicals increases. The existence of Ht OH, and HO 2 Card 2/6 22440 S/074/61/030/005/001/001 Problem Df radiation chemistry... B103/B226 radicals has never been proved by direct experiments. The development of radiation chemistry demands a further study of intermediates by employihg modern methods. 3) Ionized and excited water molecules in the radiation- chemical conversions of dissolved substancess A. Possibilities of the redistribution of the energy absorbed by the solution3 40~ of the energy absorbed by the solution are consumed in ionization; 50% fall to the share of excitation. The limiting concentrations of the conversion products are attained the more quickly, the more reactive the substance is. The presence of a second radical acceptor has an effect upon the conversion yield of the first acceptor. The higher conversion yield occurring in concentrated solutions and in solutions of various substances, is explained by the effect produced by the excited products on the reactions. It might be *rossible to orientate the excitation energy of the solvent molecules suc.L that the effect of radiation upon the dissolved substances increases. The excitation energy absorbed by the water molecules can be transferred to the dissolved substances in the following manner: 1) by a direct collision between excited water molecules and molecules of the dissolved substance; 2) by transferring an energy quantum; 3) by resonance transfer. Card 3/6 224W S/07 61/030/005/001/001 Problem of radiation chemistry... B103YI3226 V. V. Voyevodskiy's hypothesis (Kinetika i kataliz, .1, no. 1, 14 (1961)) is mentionedp according to which the transfer of excitation energy in aqueous solutions proceeds via the hydrogen bonds, or by following the mechanism of successive transfer of active particles. B. M.A.Proskurnin's conception on coupled radiation-chemical reactions (M. A. Proskurnin, V. D. Orekhov, Ye. V. Barelko, DAN, 103, 651, (1955)). According to this conception, H- and OH recombination in liquid phase can be inhibited by simultaneously using two coupled acceptors of H and OH. The researchers explain their results by various mechanisms differing from those of the coupled acceptors. These processes, however, can be reduced to a general scheme of coupled radiolytic reactions. This assumption is proved by the system Tl + -NO- - Ce4+. (T. J. Sworski, J. Am. Chem. Soc. 77, 4689 (1955)). 3 The system studied by Sworski may serve as an example for the effect of coupled acceptors of H atoms (Ce4+) and of OH radicals (T1+). Maximum yields in radiolyzed water molecules have been obtained frequently with solutions of substances being energetic acceptors of both radicals (H and OH), as, e.g., ON(SO )2 -or p, pf-disulfo-a-a,-diphenyl- ~-picryl- 3 2 Card 4/6 224W S/074J61/030/005/001/001 Problem of radiation chemistry... B103/B226 hydrazyl. C. Effect of two kinds of exoited water molecules on the reao- tions. Since a maximum yield of one of the two radicals has been obtained also without a coupled acceptor, it is assumed that in aqueous solutions two types of excited water molecules are produced, differing from each other by level and kind of excitation. During the dissociation of the excited molecule, the radicals of type I may retire from one another, as to react with the dissolved substance. In order that type II enters into reaction, either the presence of coupled radical acceptors or of an ac- ceptor of both radicals is necessary. Type II of the excited water mole- cules might have a-triplet structure. The yield 9f radical reaction proddets in the irradiation with gamma rays of Cooof in the presence of a competitive acceptor, linearly depends on the cube root of concentration of this acceptor. The author assumes that in this case the rate of forma- tion of the molecular product is depandent on the rate of the competitive process. The study of these dependences for the explanation of track reactions is very promising. Some conclusions are drawn: With increasing concentration of the radical acceptor, the reaction conditions of radical products are establishedt 1) from ionized; 2) from excited water mole- cules. As the radical products are differently distributed, the com- Card 5/6 224W S/07 61/030/005/001/001 Problem of radiation chemistry... B103YB226 peti,tion conditions of the H + Kk and H * R processes (Ak - acceptor) are changed. Mentionis made of the nitrate - water system, the reduction mechanism of which remains unchanged in concentrations of I - 15-9 moles. The present experimental material cannot be unambiguously explained by the conceptions of several researchers. One of the basic problems is the explanation of the part of excited states played in the conversion processes due to radiation, as well as of the ways of transfer of absorbed energy between the molecules in solution'-s.

TITLE: Electron paramagnetic resonance spectra and kinetics of accumulation of products formed during radiolysis of frozen aqueous sodium nitrate solutions PERIODICAL: Zhurnal fizicheskoy khimii, v. 35, no. 7, 1961, 1465-1473 TEXT: The authors studied the reactions taking place during radiolygis by means of an e.p.r. spectrometer, using dose rates between 3.103-3-10 r/sec. Cc 6o with an activity from 30 to 18,000 g-eq. Ra was used as emitter. In order to identify the resonance lines and to study the mechanism of radiolysis the radiolysis of sodium nitrate with admixtures of oxyge-71, glycerol, ethanol and other alkaline salts was also studied. The working temperature was -1450C. The spectra did not change with changing conoentration of.the nitrate solution (2-lo-3-5M). At this temperature the mobility of the radicals formed from water is high enough to enable them to react with the solutes. The radicals formed in radiolysis are stable. In alkaline and Card 1/4 26336 S/07 6j/035/007/0055/019 Electron paramagnetic resonance B127XB102 neutral solutions at least three radicals were detected. Radicals I and II are formed from NO- (Radical I: NO*. Radical 11; HNO3.) Substitution of 2 H by D decreases tg; width of the line of II, Ai interaction of the unpaired electrons of II with the surrounding protons apparently affects the line width. The line of II disappears in acid solution; it is not observed in solutions with N02. A line observed having triplet structure could not be identified with certainty but is assigned to N02' In neutral and acid NaNO3 solutions the spectrum of a radical IV was observed. The line of the radical V is only found in alkaline solutions. IV is assumed to be a peroxide radical formed from: NO- + OR --)HON(00*)O-. OH is taken from 'he water. 3 4 The broad line of V might be indicative of hydrated 02. IV disappears when ethanol or glycerol are added to the sodium nitrate solution. A single line with a g-factor of 2-04 appears in the presence of 02 in NaN02: a + 02 - H02. In neutral medium this radical will react with the solutes, in alkaline solution the following reaction will take place: HO + OH- - 0- - H 0.

By addition of glycerol or alcohol the yield of radicals could be increased by! 4W4. The sensitizing'effect may be compensated by the tendency of the radicals to recombine to water. The yield 6f moleculdr H at liquid- 0 2 nitrogen temperature was 6,15 m lecule/loo ev in pure frozen water. Obviously, the atomic H is then sufficiently mobile either to recombine or to react with the solutes. Other radicals formed'in irradiation of ice (especially 0111) are stable only down to -1600C. Dipsolved cirbon dioxide seems to stabilize H. The yield of radicals and nitrite ions is about the same. The radical yield does not depend on the.nature of solutions being satu'rated with gas. Alkaline solutions exert a sensitizing effect on tb6' radical formation. Mention is made of It. A. P3~oskurnin, N. Ya. Buben, V. I. Smirnova, T. A. Simonova,.V. V. Voyevodskiy.
