Abstract

In the present work, decoloring of acid dye solution by the diethylaminoethylated cellulosic adsorbents($CA_{DASE}$) was studied with the aim of developing polymeric adsorbents for the treatment of colored wastewaters. To prepare the cellulosic adsorbents, the $CA_{DASE}$ cellulose and polyvinyl alcohol mixture(80 wt% cellulose content) were crosslinked by tryacryloyl hexahydro-s-tryazine(TAHHT), ammonium phosphate and then treated with solutions containing sodium hydroxide and 2-diethylaminoethyl chloride. Batch and flow method were employed to determine decoloring capacity of C $A_{DEAE}$ for C.I.acid yellow 49. $CA_{DASE}$ exhibited much better desorption capacity than activated carbon. Furthermore, the exhausted $$CA{DASE} could be readily regenerated by washing with dilute sodium hydroxide.
