Abstract
The transfer of K+ from water to dichloroethane assisted by dibenzo-18-crown-6 has been studied at a liquid–liquid interface supported at the tip to a micropipette. The apparent electrochemical rate constant and apparent charge-transfer coefficient have been determined by analysis of the quasireversible steady-state wave observed. A kinetic model is proposed and the true electrochmical rate constant for the complexation reaction is thereby calculated.Keywords
