Abstract  

The permeation of various elements through a tributyl phosphate (TBP)-decalin membrane supported on a microporous polytetrafluoroethylene sheet was studied using a multitracer. Permeation rates of elements from feed solutions to distilled water as a receiving agent were determined by changing the HCl concentration in feed solutions. An increase in the transport was observed for most of the elements studied with increasing HCl concentration in the feed solutions. Among them, Fe, Zn, Se, Zr, Nb, Te, Hf and Re gave relatively high percentages of permeation from 4-12 mol.dm-3 HCl feed solutions. The permeability coefficients of these elements were determined.
