a kinetic investigation of a carrier-mediated transport through a bulk liquid membrane

چکیده
the kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-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 [k·l]+scn¯ through the liquid membrane stagnant films at the interfaces. it illustrates the connection between liquid-liquid extraction equilibrium data and 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.

Kinetics of Cr(III) ions transport through a bulk liquid membrane containing dinonylnaphthalenesulfonic acid (DNNSA) as a carrier, flowing over aqueous phases, has been examined. Special attention has been paid to the effect of the membrane's velocity flow on the chromium concentration decrease in a feed phase. For the description of relationships of chromium(III) concentration in particular ph...

The kinetics of Cu(II) transport through a bulk liquid membrane with different membrane materials was investigated in this work. Three types of membrane materials were used: fresh cooking oil, waste cooking oil and kerosene, each of which was mixed with di-2-ethylhexylphosphoric acid (carrier) and tributylphosphate (modifier). Kinetic models derived from the kinetic laws of two consecutive irre...
