FLUORIDE REMOVAL FROM WATER BY ADSORPTION ON NATURAL ADSORBENT PREPARED FROM BEET ROOT LEAVES

Abstract

Among all the quality parameters, Fluoride is one of the water quality parameters of concern. Dueto its dental and bone deficiency to living entities the WHO limits the fluoride content that shouldnot be greater than 1.5 mg l–1. In the present study investigation is performed the removal abilityof beet root leaves as adsorbent for removal of fluoride ion from aqueous solution. The optimumconditions were studied to get maximum adsorption. It was observed that maximum removal offluoride ion was at pH 7.5, maximum removal was achieved upto 62%. Removal of fluoride wasconfirmed by EDAX. Kinetics data was best fitted for First order kinetics.
