PHOTOMETRIC DETERMINATION OF Zr IN Hf BY ARSENAZO III (in Russian)

Journal Article · · Zavodskaya Lab.
OSTI ID:4841017

Properties of colored Hf and Zr complexes with arsenazo III and their reactions to increased acidity are analyzed. Small concentrations of Zr (0.2% and over) may be determined in metallic Hf on the basis that the optical density of Hf complexes with arsenazo III rapidly diminishes at 4N HCl while the optical density of Zr complexes does not.
