Abstract

Background: Fluoride is like a double edge sword, when ingested in lower amount benefits the health while ingested in larger amounts cause health hazards, defluoridation is the technique used to remove fluoride from water. Household methods of defluoridation using adsorbent materials are cost effective than other methods used to remove fluoride from water. The aim of the study is to determine the efficacy of low-cost household materials Tamarindus indica, Moringa oleifera, and Tinospora cordifolia for defluoridation of water. Material and Methods: An in vitro study was done using materials such as T. indica, M. oleifera, and T. cordifolia. The materials were obtained in powder form of particle size of 75 micron. Standard solution was prepared using sodium silicofluoride (NaSiF6 ), which was weighed and dissolved in distilled water and diluted to 10 ml. The solution was then diluted to make ten parts per million standard solutions. The standard solution was filtered through the two tire filtration process and analytical determination of fluoride was done after treatment of water with the 2% (W/V) adsorbents powder filtration. Results: The results of the study showed that T. indica was found to have defluoridation capacity of 80% at neutral pH as compared to other household materials such as M. oliefera and T. cordifolia 70% and 67%, respectively, reduction in fluoride concentration at acidic pH. Conclusion: The present study concluded that among the aforementioned plants, T. indica powder was found to be the best domestic material for defluoridation property. It can be adopted for the defluoridation method in villages as it is cheaper and easily available biosorbent in Indian households.
