چکیده مقاله:

The present study was carried out to investigate the effect of chitosan for the removal of Direct Red 23 (DR 23) from contaminated water in comparison with activated carbon by using batch adsorption studies. In present study chitosan has been selected as adsorbent because of advantages such as high adsorption capacity, potential of variety of pollutants removal, non toxic, abundant availability and 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 activated carbon has investigated. Results showed that removal of dyes increased with increasing contact time, adsorbent dosage, temperature and dye initial concentration decreasing. Also it may be concluded that chitosan was more efficient than activated carbon.
