REMOVAL OF COLOR FROM EFFLUENTS USING POLYAMIDE-EPICHLOROHYDRIN-CELLULOSE POLYMER .2. USE IN ACID DYE REMOVAL

The ability of polyamide-epichlorohydrin-cellulose (PAE-cell) to remov e various acid dyes from aqueous solutions was investigated. The class es of acid dyes included the milling type, levelling type, and metal-c omplex type. Operational conditions such as PAE-cell type, dye type, P AE-cell particle size, dye bath flow rate, filling density in the colu mn, initial dye concentration, pH of solution, and adsorbent mass were studied. The results show that these PAE-cell polymers exhibit better capacity for acid dye removal than some commercial activated carbons. (C) 1993 John Wiley & Sons, Inc.
