REMOVAL OF FLUORIDE FROM GROUND WATER BY USING TREATED BARK OF PHYLLANTHUS EMBLICA (AMLA) TREE

Fluoride is the essential element for dental health and growth of bones as well whereas excess quantity of fluoride creates a problem of human health. It is very much essential to control the excess level of fluoride concentration (WHO) <1.5 mg/L. Several methods and techniques were used by researchers throughout the decades for the control of fluoride ion. This research paper addresses Phyllanthus Emblica (Amla) bark for the estimation of fluoride. The Physico?chemical characterization followed SEM, FTIR, CHN analysis etc. The batch experimental study followed the adsorption parameters, pH (6-8), dose (0.5-5 mg/L), initial concentration (5mg/L), particle size (75-300μm) and time of contact (60-720 Min.). It follows Langmuir & Freundlich.
