✦ Synopsis

Complex-impedance variations of the ion-exchange resin DOWEX 50X8 with the type of counterion allow one to follow the Cu2+/H ÷ and Ca2+/Na ÷ exchange reactions without chemical analysis of solutions. Frequency and ionic strength effects are specified. This method is effective for following the Na+/K + separation by displacement of Ca 2÷ ions.
