چکیده
|
The kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18crown-6 (l) through a bulk liquid membrane is studied experimentally and theoretically. the proposed model is based on the assumption of a pure diffusion of the complex salt [kelj+scnthroughthe liquid membrane stagnant films at the interfaces. it illustrates the connection between liquid-liquid extraction equilibrium data anf! transport rates. the evaluation of the transfer coefficient allows to evaluate the organic stagnant films thickness, the stationary state transport rate and the time lag.
