Abstract

The major problem in textile industries is the effluent treatment particularly the removal of dyes. Polymer adsorbents are widely tried in the removal of dyes from industrial effluents. Chitosan, a biopolymer derived from chitin is most abundantly present in the exoskeleton of crustaceans including prawns, shrimps, lobsters and crabs. In the present study, efficiency of chitosan as a biosorbent in the treatment of textile dye effluent has been analyzed. It has been found that chitosan is very effective in biodecolourisation of textile dye effluent collected from the local dyeing units. It has also reduced the physico-chemical parameters to the permissible limits. The results have been confirmed using HPLC and statistical analysis. From the present study it is found that chitosan isolated from the chitin of prawn shell waste is very effective in terms of biodecolourisation of textile dye effluent as well as cost.
