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
