REMOVAL OF FLUORIDE FROM GROUND WATER BY USING MODIFIED BARK OF TERMINALIA CHEBULA (HARITAKI)

In this research investigation, the Modified bark of Terminalia Chebula (MTC) was found a predominant promising bio-adsorbent for the removal of fluoride content from aqueous solution. The method of adsorption used in batch experimental analysis for pH (2-12), dose (0.5-5.0 g/L), time interval (60-720 Min.), initial concentration (2.5-15 mg/L),particle size (150-600?m). The maximum removal obtained at pH range 6-8 for the optimal conditions of other parameters. The data fitted well in the Langmuir and Freundlich isotherm.
