| dc.description.abstract | Carica papaya seed (CPS) waste was used as an adsorbent for the removal of malachite green and was studied in batch mode the effect of agitation time and initial dye concentration, adsorbent dosage and pH were examined. The study revealed that the amount of dye adsorbed (mgg-1) increased with increase in agitation time and reached equilibrium after 35 minute. for dye concentration of 2.00-10.00 mg/l. the adsorbent dosage of 1.00 g/60.00ml and pH 8.0 were found to be the optimumformaximumfor maximum dye removal. The batch mode adsorption followed both the Langmuir and Freundlich isotherms. The pseudo first and second order kinetics model provided the best correlation of the equilibrium data. The adsorption kinetics of malachite green showed that the pseudo first order kinetic model provided the best correlation of the equilibrium data. This study implies that it is possible to develop a dye removal system using carica papaya seed, which occur as a waste in the environment. 2011 Trade Science Inc. - INDIA | en_US |
