In this study, an experimental study on the transport of methylene blue ( MB) through bulk liquid membrane ( BLM) is done and thereby best set of solvent, operating conditions, and mode of transport that would yield optimum performance of the BLM are identified. Therefore, a kinetic study of MB transport from an aqueous donor phase into an aqueous acceptor phase through a BLM containing calix arene octacarboxylic acid ( COCA) derivative as a carrier was studied. The influence of type of solvent, stirring speed, effect of NaCl weight in feed phase and temperature were investigated. The kinetic parameters ( k(1), k(2), R-m(max), t(max), J(d)(max), J(a)(max)) were calculated for the interface reactions assuming two consecutive, irreversible first-order reactions. In this study, the experiments demonstrated that COCA derivative is a good carrier for MB transport through liquid membranes.
