Abstract

Influence of halide ions (chloride-, bromide-) on the solvent extraction of ion associates of cadmium with malachite green and fuxine has been studied. The optimal conditions of formation and extraction of ion associates have been examined, medium acidity, nature and concentration of halide ions, basic dyes. Comparative characteristic of halogenide complexes of cadmium is given, according to its solvent extraction complexes: iodide > bromide > chloride. The developed method with bromide complexes was used for determination of cadmium contents in tobacco.The method in more selective, but small sensetive, than method with iodide complexes.
