The application of chelating polymers for the removal of arsenic compounds from water

Abstract

A review of the literature on the possibilities of the application of chelating polymers containing various functional groups (Table 1) for the removal of highly toxic and environmentally hazardous arsenic(III) and (V) compounds from water in different parts of the world has been presented. The mechanisms of direct coupling of arsenates and arsenites by the functional groups of the polymers, and also of the so-called ligand exchanging has been discussed (Figs. 1, 2). The influence of factors such as solution flow rate through the polymer bed, water pH value and the presence of other ions on the efficiency of coupling the arsenic compound was evaluated. The possibility of regeneration and multiple use of the chelating polymers was discussed.
