| Abstract: | Facilitated transport of lead ion across a bulk liquid membrane by three calix4]arene derivatives, as ion carriers, dissolved in CHCl3 has been investigated. Transport kinetics of lead ion using calix4]arene derivatives carriers in liquid membrane have been briefly discussed. The influences of fundamental parameters affecting the transport of lead ion including ion carrier concentration in the membrane phase, stirring speed of membrane, time of transport have been studied. Transport of lead ion occured al... |
