Volumetric estimation of metals via precipitation with organic reagents

Summary A rapid volumetric method for the estimation of nickel has been proposed. The procedure consists of the precipitation of nickel with dimethylglyoxime followed by the hydrolysis of the oxime in hydrochloric acid solution and the titration of hydroxylamine formed with permanganate using cupric chloride as catalyst.Published by permission of the Director, Mines Branch, Department of Mines and Technical Surveys, Ottawa, CanadaAt present National Research Council of Canada Post-doctorate Research Fellow
