Removal of Methylene Blue from aqueous solution by Cynodon dactylon leaf powder

P. Selvapandian, K. Ananthakumar

Abstract :

In this study, we reported the removal of Methylene Blue (MB) by Cynodon dactylon leaf powder (CDLP) using batch technique. Adsorption studies are conducted in different initial dye concentrations, adsorbent doses and temperature. The removal of MB is increases with decrease in concentration of dye. The experimental data were analysed by Langmuir, Freundlich and Temkin models. The adsorption capacity (Qo) of CDLP was found to be 24.57 mg/g. From the effect of temperature, thermodynamic parameters such as the free energy change (?Go), enthalpy change (?Ho) and entropy change (?So) were determined.
