“…Previous studies (5, 6, 14, 15) have established the optimum conditions for the rapid quantitative precipitation of the Group IVB metals with cupferron. The amperometric titration of titanium, zirconium, and hafnium wfith cupferron has been described (5,15).…”

The importance to the atomic energy program of reasonably rapid, simple, and accurate methods for the analysis of mixtures containing uranium, niobium, and zirconium prompted an investigation of polarographic and amperometric procedures for this purpose. Mixtures containing uranium and zirconium can be analyzed by polarographing an aliquot of a 10% sulfuric acid solution between 0.0 and -0.5 volt to determine uranium, and titrating another aliquot amperometrically with standard cupferron solution at -1.0 volt to determine zirconium.In mixtures containing uranium, niobium, and zirconium, the zirconium is separated as the phosphate from hydrogen peroxidesulfuric acid solution, and the suspended phosphate is titrated amperometrically with cupferron.

In connection with the determination of small amounts of zirconium in complex samples, procedures have been developed for bringing various types of sample into solution and removing possible interferences, which procedures allow pbromomandelic acid to be used as a precipitant for the 6nal recovery of zirconium for gravimetric measurement. The applicability of these procedures, which are described in detail, has been investigated by the analysis for zirconium of a variety of refractory mineral and metallurgical samples.
