چکیده انگلیسی
Waste-water from the textile industry is one of the major sources of contamination, causing serious health problems. The present study involves activation of bentonite clay using different acids and investigates the adsorption efficiency of acid activated bentonite clay for the removal of Mordant Red 73 from textile waste-water. Change in any functionality before and after activation was evaluated by FTIR analysis. Whereas, the surface morphological properties were observer by Scanning electron microscope. EDS analysis confirmed the leaching of Ca+2 and Mg+2 as a result of acid activation. Effects of different parameters i.e. effect of adsorbent dosage, contact time, pH and temperature and their effect on adsorption capacity were studied. Thermodynamic parameters explored the endothermic nature of adsorption. Pseudo-second order model was found to fit best for the equilibrium adsorption data.
