摘要
Recently,there has been development of highly sensitive spectrophotometric method for determination of rhodium taking advantage of the ion-associate involving basic dyes.The anionic chloride and chlorostannate(Ⅱ)complex of rhodium with malachite green cation is used for flotation——spectrophotometric determination of rhodium.In this paper a method is reported for the spectrophotometric determination of rhodium based on the Ion-associate formed by the anionic chloride and chlorostannate(Ⅱ)complex of rhodium[Rb2Cl2(Sn Cl3)4]4-with the basic dye——crystal violet cation in aqueous solution in the presence of polyvinyl alcohol.
