title: Aluminum nitrate (Al(NO3)3) as defluoridating agent in drinking water soil pots (vessels of earthenware).
abstract: Presence of fluoride in drinking water above (and sometimes even below) permissible limit (1.5 ppm according to WHO) leads to fluorosis. Aluminum salts are commonly used as coagulants in water treatments. Aluminum fluoride is less toxic than other fluorides. The concentration of fluoride was determined by the fluoride ion selective electrode method. In this study, Al (NO3)3 was incorporated in different amounts in soil and prepared soil pots by the mixture. It is observed that these soil pots remarkably decrease the concentration of fluoride in drinking water. Langmuir and Freundlich isotherm studies were also carried out.
