REMOVAL OF FLUORIDE ION FROM AQUEOUS SOLUTION USING MURINGA OLEIFERA ADSORBENTS. Viola Rose, B. Indirani and G. Allen Gnana Raj
The presence of toxic fluoride contaminant in ground water systems, arising from fluoride-bearing rocks (Meenakshi et al., 2004) and from the discharge of untreated fluoride containing effluents is one of the most important environmental problems currently being faced by human race. Adsorption is one of the effective techniques for the removal of fluoride from aqueous solutions. In the present study, adsorbent is prepared from a nutritious leafy vegetable, Muringa oleifera leaves and studies are carried out for fluoride removal. Batch sorption studies demonstrate that the adsorbent prepared from Muringa oleifera leaves has a significant capacity for adsorption of fluoride from aqueous solutions. The parameters investigated in this study include pH, temperature, initial fluoride concentration, contact time and adsorbent dose. From this study, the adsorption of fluoride was found to be high at neutral pH.
