Abstract
Recovery and transport of thorium(IV) from HNO3 medium using a polymer inclusion membrane (PIM) containing di (2-ethylhexyl) phosphoric acid (D2EHPA) as the carrier, and polyvinyl chloride (PVC) as polymer were studied. Taguchi L-16 orthogonal array was used to evaluate the effects of the membrane’s carrier content, pH, strip phase type and concentration, and initial concentration of Th(IV) on the cation transport. Using a 45% (m/m) D2EHPA-55% (m/m) PVC PIM, Th(IV) is completely separated from a number of common metal cations. Studies on the transport kinetics and the stability of the membranes were also performed. The results showed that the PIM has excellent stability.
