Transport of methylene blue through bulk liquid membrane containing calix[8]arene derivative

Abstract

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[8]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 (k₁, k₂, , t_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.
