有機試薬による金属クロマトグラフ分析法（第2報）パラジウムの分析法

0.005r of paladium is detectable by the dithizone chromatographic method. Its absorption band is bluish green and situates between the brownish purple hand of nickel and violet band of cobalt. A micro amount of paladium, such as contained in rocks, can be determined by the dithizone chromatographic method. Interfering ions are eliminated by the combination of copper sulfide and nickel dimethylglyoxime methods. Analytical methods of paladium, nickel, cobalt, and copper by paper chromatograph were investigated.
