Abstract :
The ability of lateritic soils to remove fluoride from water has been studied. Important issues considered in the study include the relation between the mineral composition of soils and their ability to remove fluoride, The effect of thermal treatment of the soil on fluoride removal the predominant fluoride containing species remain in the treated water and the possible mechanism of fluoride removal by lateritic soils. Fluoride contamination in drinking water due to natural and anthropogenic activities has been recognized as one of the major problems worldwide imposing a serious threat to human health. Presence of fluoride in low concentration 1.5 mg l is beneficial to the people for the calcification of dental enamel and maintenance of healthy bones. On the other side, its presence in higher concentration become a monster and can cause dental, skeletal fluorosis and also non skeletal problems. Among several treatment technologies applied for fluoride removal, adsorption process has been explored widely and offers satisfactory results especially with mineral based and or surface modified adsorbents. It is evident from the literature survey that various adsorbents have shown good potential for the removal of fluoride. However, still there is a need to find out the practical utility of such developed adsorbents on a commercial scale, leading to the improvement of pollution control. Many investigators conducted experiments and developed various low cost technologies to remove fluoride from water and wastewater. However, selection of appropriate treatment method depends on local situation. In this experiment fluorine removal from water by adsorption is studied. Optimum conditions of the experiment have been expressed. Environmental aspects of the adsorbent have been analysed Sunita Singh | Dr. Sushil Kumar Singh "Removal of Fluoride Using Brick Chip by Adsorption Prepared from Laterite Soil Area of Bihar & Jharkhand" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-5 , August 2018, URL: https://www.ijtsrd.com/papers/ijtsrd15664.pdf Paper URL: http://www.ijtsrd.com/other-scientific-research-area/enviormental-science/15664/removal-of-fluoride-using-brick-chip-by-adsorption-prepared-from-laterite-soil-area-of-bihar-and-jharkhand/sunita-singh
