Adsorption Analysis, Characterization And Equilibrium Study Of Pigeon Pea Seed Coat (Ppsc) For The Removal Of Fluoride From Ground Water

Abstract

Fluoride is an essential nutrient for the human body at low concentrations. Fluoride in drinking water can be either beneficial or detrimental to health depending on its concentration. Removal of fluoride from synthetic solution using the peels of Pigeon Pea Seed Coat (PPSC) was studied in a batch experimental analysis. The results of the batch adsorption experiments demonstrated that the maximum fluoride removal was obtained at pH of 6.5. In adsorption Freundlich and Langmuir models were studied and found the best
fitted model was Langmuir. The adsorption capacity of PPSC was found on a dose of 3.0 g/L. The adsorption process was exothermic in nature. The parameters are tested and found all within limit of BIS 10500-1991. The effects of coexisting ions were studied. Cost of (PPSC) was analyzed and found very cheap.
