Abstract
The faradaic transfer behaviour of the charged species formed in the s ystem of Cd2+ and some other divalent metal ions extracted by 1,2-dich loroethane with quinolin-8-ol (HQ) as complexing agent was examined el ectrochemically. It follows from the experimental findings that after the HQ distributes from the organic into the aqueous phase, M(DQ)(2)(2 +) and neutral species are formed there and the former is involved in the faradaic transfer process from the aqueous to the organic phase.
