The removal of color from effluents using polyamide‐epichlorohydrin‐cellulose polymer. I. Preparation and use in direct dye removal

A novel series of adsorbents have been prepared by reacting adipic acid, diethylenetriamine, epichlorohydrin, and cellulose. The structural features of these polyamide‐epichlorohydrin‐cellulose (PAE‐Cell) polymers have been confirmed by IR analysis. The ability of PAE‐Cell polymers to adsorb direct dyes from aqueous solution has been evaluated in a fixed bed column system. These PAE‐Cell polymers have been found to exhibit a better capacities for direct dye removal than some commercial activated carbons.
