| Abstract: | The influence of swelling and stripping acidity on the mass transfer coefficient based on water phase and the inner diameters of membranes were studied with P507 kerosin HCl Sm as working system in the two different kinds of hollow fiber membranes. The effect of extractant concentration and H concentration in aqueous phase and Sm 3 concentration on extraction rate were discussed and corresponding reaction series were obtained. According to the investigations on the interfacial kinetics, the reaction kinetics equation and reaction rate constant are obtained. |
