| Abstract: | The transport of europium through a porous supported liquid membrane (SLM) containing PC- 88A (EHPNA) and Versatic 10 (VA 10) as'immobilised carriers has been carried out. The results demonstrated that transport increases with increasing stirring speed, and reaches a constant value beyond a certain rotation speed. The permeability coefficient increases with the increase in· carrier concentration in a certain range. The dependence of permeabilities on the pH of both the source and receiving solutions have been explored. The permeability coefficient has been calculated by taking into account the mass balance. The effects of compIexing agents such as succinic, malonic and citric acid on permeability coefficient of europium has been investigated. Under similar experimental conditions the effect of complexing agents on permeation of europium has been found as: citric acid > succinic acid > malonic acid. Permeation coefficient of europium has been found greater with PC-88A in comparison with that of Versatic 10. The effect of complexing agents using in receiving phase has been explored. The mechanism of transport of europium in supported liquid membrane has been suggested. The developed methods have been used for the exploration of its utility for synthetic samples. |
