| Abstract: | The possibility of studying the speciation of rhodium(III) by capillary electrophoresis was shown using a model solution of rhodium(III) in 0.1 M HCl as an example. The revealed rhodium species were identified by their absorption spectra. The effect of the pH, ionic strength, and metal (Me) cation in the HCl–MeCl supporting electrolyte on the migration parameters and the speciation of rhodium(III) in the solution was studied. |
