Defluoridation of contaminated drinking water using neem charcoal adsorbent: Kinetics and equilibrium studies
Drinking water is often the main source of fluoride intake by humans, especially in areas where their concentrations in groundwater and/or surface water is high. Endemic fluorosis is present in at least 20 states of India, affecting more than 65 million people including 6 million children. Fluoride ion (F) concentrations in India’s groundwater vary widely, ranging from 0.01 mg/L to 48 mg/L. Def...
متن کاملDefluoridation of Drinking Water : Efficacy and Need
Fluorine is the 13 most abundant naturally occurring element in the Earth’s crust and is the lightest member of the halogens. It is the most electronegative and reactive of all the elements and as a result, elemental fluorine does not occur in nature but found as a fluoride mineral complexes. Exposure to fluoride beyond the recommended level for longer duration causes fluorosis. Several physica...
متن کاملDefluoridation Of Water by Moringa Oleifera- A Natural Adsorbent
The water available for daily consumption may be contaminated by natural sources or by industrial effluents. One such a contaminant is fluoride. Exposure to fluoride in drinking water has a number of adverse effects on human health. One of the naturally available alternatives for defluoridation of water is Moringa Oleifera. Using colourimetric method, tests were conducted to get optimal values ...
متن کاملDefluoridation Of Drinking Water Merits of Alternative Technologies
The crippling malady of fluorosis not only affects the bones and teeth, but every tissue and organ of the body, leading to death after prolonged illness. It is a problem of public health importance. Although the disease had been known to exist in India as early as the 1930s it was not identified as a national health problem till India became independent. Perhaps the magnitude of the problem and...
متن کاملNatural Zeolites Application as Sustainable Adsorbent for Heavy Metals Removal from Drinking Water
Background: There are great resources of natural zeolite in Iran. Zeolite, an inorganic ion-exchanger, may be used as a suitable technical-economical solution for water treatment in many regions of Iran. In this study, the characterization of natural zeolite natrolite and the feasibility of removing hardness, cations, and anions were investigated. Methods: First, zeolite composition and type...
