title: Biacetyl monoxime glycinimine as a selective reagent for palladium and nickel.
abstract: Biacetyl monoxime glycinimine is proposed as a new reagent for the selective gravimetric and extractive photometric determination of Pd(II) and Ni(II). The reagent forms yellow and rose-red water-insoluble complexes with Pd (pH 0.5-5.5) and Ni (pH 5.0-11.2) respectively. The complexes can be used for direct gravimetric determination or extracted with molten naphthalene. The solidified naphthalene-complex mixture is dissolved in chloroform and measured photometrically. The effects of experimental variables and diverse ions are reported. The proposed reagent offers better selectivity than dimethylglyoxime.
