THE COLORIMETRIC MICRODETERMINATION OF TITANIUM AND VANADIUM IN URANIUM COMPOUNDS USING BENZOYLPHENYLHYDROXYLAMINE
Separate but similar methods for the rapid microdetermination of Ti and V in U compounds were developed. Titanium(IV) and vanadium(V) both react with benzoylphenylhydroxylamine (BPHA) to form highly colored complexes that can be extracted into chloroform from 8 M or 4 M hydrochloric acid, respectively. The Ti analysis is then completed colorimetrically by measuring the color of its yellow BPHA complex at a wave lengih of 420 M . For the analysis of V, the color of the violet BPHA complex is measured at a wave length of 530 m . The methods offer advantages over other available methods because of the selectivity and sensitivity of the reagent for the two elements. Concentrations of Ti as low as 0.2 g/g of U can be determined. Ten micrograms of Ti can be analyzed with no significant bias and a limit of error of 450 deg C in a 6%. Concentrations of V as low as 0.2 g/g of U can be determined. Five micrograms of V can be analyzed with a limit of error of 450 deg C in a 6%. The methods are also applicable to the analyses of a wide variety of other materials. (auth)
