説明

The distribution equilibria between cadmium (II) chloride, bromide, iodide and perchlorate complexes and the cation exchange resin in aqueous acetone solutions have been investigated. Formation constants of cadmium halides or perchlorate have been calculated from the distribution coefficients of cadmium in aqueous acetone solutions containing 10, 20, 30 and 40 v/v% water. Cadmium concentrations of the solutions have been measured by the atomic absorption spectrophotomer equipped with a carbon tube atomizer. The logarithmic values of constants in 10 v/v% aqueous acetone are: β1Cl =6.25, β2Cl =11.05 and β3Cl =14.59 for cadmium chloride, β1Br=6.97 and β2Br=10.35 for cadmium bromide, β1I=7.02 and β2I=11.80 for cadmium iodide, β1ClO4=2.18 for cadmium perchlorate. Formation constants of cadmium chloride are lower than those of cadmium iodide because of soft basicity of cadmium.
