Adsorption Isotherm Studies in the Removal of Malachite Green Dye from Aqueous Solution by Using Coal Fly Ash


Author(s): Gopal Gehlot, Sanjay Verma, Sarita Sharma, Neeraj Mehta

Abstract: In this paper the effectiveness of coal fly ash for the removal of Malachite Green dye from aqueous solution was evaluated using different isotherm models. Adsorption data were modeled using the Langmuir, Freundlich and Temkin adsorption isotherms. The results showed that the optimum conditions for the dye removal at a pH of 8, an adsorbent dose 2 gm, contact time 2 hours and a temperature of 32 °C. Maximum adsorption capacity of coal fly ash was found to be 2.23 mg/g. The result indicated that coal fly ash is an attractive adsorbent for removing basic dye from aqueous solution.
