Abstract

Potentiometric selectivities of a liquid anion-exchange membrane containing triphenyltin chloride (TPTCI) to several inorganic anions were evaluated via measurements of the membrane potential of a bi-ionic system, also called bi-ionic membrane potential. Addition of TPTCI to the liquid anion-exchange membrane, based on the quaternary ammonium salt, gave rise to a quite different selectivity pattern from the so-called Hofmeister anion series observed for the liquid anion-exchange membrane. An additivity rule of the bi-ionic membrane potential was observed to hold for the Liquid anion-exchange membrane containing TPTCI. Thus, the following multiple chain rule was derived for selectivity coefficients; k(l,n)(pot) = k_1,2(pot)·k_2,3(pot)...k(i,(i+1))(pot)...k(n-1,n)(pot), where k(i,i+1)(pot) is the selectivity coefficient of the membrane for the (i + 1)th ion over the ith ion.
