A procedure for extraction- chromatographic separation and spectrophotometric determination of indium has been developed. This proce- dure gives more clear-cut separation and higher accuracy and reproducibility than ordinarily used separation by solvent extraction with butyl acetate. Besides, it can be used to separate and determine cadmium simultaneously.展开更多
