lution up to a ratio of.Sb:As = 1:6 does not
interfere with the Sb determination. For the
microdeterminntion of Sb3+, to a volume of
0.5-4 mi of a methanol solution of SbCI-A(+AsC'3)
are added 1 ml of a buffer solution (150 gr

ABSTRACT:
The purpose of the investigation was a)
the detection of a

more general functional group for ?d than that
given by

L. M. Kullberg (Ref 3), and b) to devise a sensitive photo-

metric method of palladium determination also in the presence

of
platinum. As functional groups the following are given

(Table 1)
