P-NITROSO ARYLAMINES AS REAGENTS FOR the SPECTROPHOTOMETRIC DETERMINATION OF PALLADIUM.

P K GUPTA

Abstract


The effect of substitution in p-nitroso arylamines has been studied. Two reagents, viz., p-nitrosodiphenylamine sulphonic acid and p-nitrosophenyl u-naphthylamine have beensynthesised and investigated as possible reagents for the determination of palladium. The first compound gives a water soluble complex which can be ust.d directly for the quantitative estimation of palladium. The latter reagent p-nitrosophenyl a-naphthylamine shows greater selectivity as compared to ponitrosodimethylaniline.

Keywords


p-nitroso diphenylarnine sulphonic acid, p-nitrosophenyl a-naphthylamine, palladium determination.
