Chaudry, M. Malik, Munir Ahmad] Transport study for Ti(IV) ions using di-2-ethylhexylphosphoric acid (D2EHPA) (carrier)-CCl4 (diluent) liquid supported membrane in microporous polypropylene hydrophobic film has been performed. The parameters studied are effects of carrier, H2SO4, stripping agent (NH4F) concentrations and temperature variation on flux and permeability coefficients of the metal ion. The optimum concentrations of transport found are 2.04 mol·dm−3 D2EHPA, 1.0 mol·dm−3 H2SO4 in the feed and 1 mol·dm−3 NH4F as stripping agent. The maximum flux and permeability coefficient determined are 1.32·10−5 mol·m−2·s−1 and 8.02·10−12 mol·m−2·s−1, respectively. The transport of this metal ion is increased with increase in temperature. The mechanism of transport appears to be based on coupled counter ion transport phenomenon. Akadémiai Kiadó, 1992 Chaudry M.
