A rapid determination of nickel in metallic uranium was possible by developing the color by addition of dimethylglyoxime in the presence of bromine water under ammonia alkaline condition and determining the absorbance at 562 mμ. Also, a simple determination of nickel was possible by dithizone extraction and absorbance measurement at 800 mμ. Or, a separatory determination of nickel and cobalt by the alumina chromatography of their dithizone complexes was presented.<BR>In order to investigate these methods, a fundamental experiment for conditions of extraction of complex dithizone salts of nickel and cobalt as affected by the pH, the concentrations of dithizone and citrate, time of shaking and the liberation from alumina column has been made and the results were given.
