Active transport of metal ions by using Schiff bases

Abstract

Schiff bases are aldehyde- or ketone-like compounds in which the carbonyl group is replaced by an imine or azomethine group. In this paper, the transport of metal ions from an aqueous solution into an aqueous receiving solution through a bulk liquid membrane containing Schiff bases as a carrier was described. Therefore, synthetic methods for the preparation of Schiff bases are also reviewed.

Keywords: Schiff bases, active transport, liquid membrane, liquid-liquid extraction.
