Paper Details

Fluorides are the major pollutants present in the effluents from various industries and ground water sources.These are highly toxic to living beings and have a hazardous effect on their health. Thus the removal of fluoride using biosorbents is a major step towards the protection of environment. Adsorption is the most effective and widely used methodand is applicable for the removal of fluoride even at low concentrations This paper presents the results of investigationscarried out for removal of Fluoride from water by using natural adsorbents i.e. Amla bark powder, Neem bark powder,Ground granulated blast furnace slag, Waste lime, Sugarcane baggase. The fluoride removal efficiency of adsorbentswas investigated by batch wise adsorption experiment. The effect of various important parameters on the % removal wasstudied to find the optimum condition for the maximum removal of fluorides. The parameters like contact time, adsorbentdose, height of column and pH were investigated. The optimum pH, height of column, adsorbent dose and contact timewere found to be 5, 15ml, 20g/l and 50 min. respectively for which there was maximum fluoride removal. All the resultswere validated on the basis of statistical analysis. All the graphs were fitted to various trend lines. Out of which theequation of most fitted trend line was adopted for the validation and deviation were observed.
