摘要

在水质参数中，氟化物是人们关注的水质参数之一。由于其对生物实体的牙齿和骨骼缺乏，世界卫生组织限制氟化物含量不应超过1.5毫克[1]。本研究考察了甜菜根叶作为吸附剂对水溶液中氟离子的去除能力。研究了最佳吸附条件。结果表明，在pH为7.5时，氟离子的最大去除率可达62%。EDAX证实了氟化物的去除。动力学数据最适合于一级动力学。

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

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 lâ1. 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.
