A Comparison of Two Spectrophotometric Methods for the Determination of Palladium in Titanium-Base Alloys.

Abstract

This report compares extraction procedures using 1-nitroso-2-naphthol and dimethylglyoxime for the spectrophotometric determination of palladium In titanium-base alloys. Dimethyglyoxime has greater selectivity hut lower sensitivity, similar precision (about 25 ppm at the 0. 2 percent level), is faster and covers a wider range of palladium contents than does l-nitroso-2-naphtho The dimethylglyoxime procedure has no interferences by any of the common or potential alloying elements, for example, cobalt, niobium, and tantalum; thus it is well suited to the determination of 0.1 to 1. 0 percent palladium in titanium-base alloys. Selectivity is improved by the presence of nitrate.
