Title

REMOVAL OF DIRECT YELLOW 9 AND REACTIVE ORANGE 122 FROM CONTAMINATED WATER USING CHITOSAN AS A POLYMERIC BIOADSORBENT BY ADSORPTION PROCESS

Abstract

The present study was carried out to investigate the effect of chitosan on the removal of Direct Yellow 9 and Reactive Orange 122 from contaminated water in comparison to activated carbon using batch adsorption studies. Chitosan has been selected as an adsorbent because of advantages such as high adsorption capacity, potential of variety of pollutants removal, non toxicity, availability, low cost and high rate of adsorption. Also the effect of contact time, initial dye concentration, adsorbent dosage, temperature and pH were examined and then removal efficiency of chitosan as compared to activated carbon was investigated. The results showed that removal of dyes increased by increasing contact time, adsorbent dosage, temperature and dye initial concentration decreasing. Also it may be concluded that chitosan was more effective than activated carbon.
