Abstract

Across the world, with an ever increasing population burden the pressures on meeting the demand supply position of quality drinking water is becoming day by day serious both from the quality and quantity aspects. In this context the fluoride contamination of ground water is a common public health problem and to control the same a large number of methods are evolving. Being an inorganic contaminant it is not possible to drive away fluoride from water by photo or bacterial degradation. Thus adsorption over cheaper surfaces is the most common economic approach for it. However, disposal of the sludge produced in the process is a major technical hurdle. In this work a common potter’s clay has been surface modified by oligomeric hydroxyl- alumina to adsorb fluoride. It was observed that fluoride removal capacity is favoured by high temperature and low pH. Adsorption kinetics as well as adsorption isotherms have been investigated. The spent adsorbent from the hydroxyl-alumina activated potter’s clay has been studied for the immobilization of the sludge. By utilizing the sludge as a raw mix substituent for cement preparation the sludge could be managed safely in the lab scale studies.
