TITLE: Determining the refractive index of zirconium and hafnium sulfate solutions
in water and in dilute sulfuric said.

TOPIC TAGS: refractive index, zirconium isulfatep haftium sulfatep temperature

ABSTRACT: The refractive indices of zirconium and hafnium sulfates in water and
dilute sulfuric acid were determined and tabulated to provide a rapid method for
determining the concentration of pure zirconium and hafnium salts in these solu-
tions. Determinations were made at 25C with 0.01 to 1.0 M zirconium and hafnium
P sulfate in water and in 3 and 4 N U2604. Determinations made at 35C indicated
temperature has little effect on the refractive index. The effect of hydrolysis
on the refractive index values was audied (+e enclosure). At,equal molar
concentrations of Zr and Hf the refractive indices of their solution at the start
of hydrolysis (within 15 minutes after vreparation of the solution) we apyrox-

-preparation) indicated that hydrolysis is stronger at the low Zr and Hf concen-
trations, vith the effect being more pronounced for Ef than for Zr. Orig. art. has:,
