A coal fly ash as an adsorbent used for removal of sulphur dye from textile wastewater. The coal fly ash required for present study collected from Bhusaval Thermal Power Plant district Jalgaon. The adsorption studies performed as a function of different concentration of dye solution, contact time, pH and different adsorbent dosages. The kinetics of the adsorption process follows the pseudo second-order kinetic model. Equilibrium data analyzed using Langmuir, Freundlich and Tempkin isotherm models. The suitability of the data in different model of isotherm is determined from correlation coefficient (R2) value and maximum adsorption capacity values. The values of maximum adsorption capacity correlation coefficient (R2) for CAF was found to be 38.46 mg/g and close to one by using Langmuir model indicating that given adsorption isotherm best described by Langmuir model as compared to Freundlich and Tempkin model . The results showed that coal-fly ash a solid waste disposal from Thermal Power Plant can used as effective low cost adsorbent for removal of sulphur dye from textile wastewater.
