Abstract

An acyclic polyether dicarboxylic acid which contains n-tetradecyl alkyl substituents at the α-position of the carboxylic acid side-arm unit was prepared by the reaction of bisphenol and 2-bromoalkanoic acid in the presence of NaH as base with quantitative yields. This ligand was incorporated into chloroform bulk liquid membranes and into polymer inclusion membranes (PIMs) composed of cellulose triacetate as support and o- nitrophenyl octyl ether as plasticizer. Selective transport of Pb2+ was observed over transition metal ions in bulk liquid membranes. The PIM showed excellent stability and durability, with very high transport of Pb2+ from an acetate buffer source phase.
