Determination of small amounts of zirconium—II Analysis of refractory samples

Abstract

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.
