Abstract
Fluoride contamination study analyzed the process of defluoridation of groundwater by using the Velvet Bean Seed Coat (VBSC). It is estimated and analyzed in batch experimental analysis. Different sets of adsorption parameters, such as effect of dose, pH, contact time, initial concentration and particle size were optimized for this study. The dose of adsorbent was observed 2.0 gm/L as a optimum dose for 15 mg/L initial concentration. At the optimum condition of pH 6.5. The percentage removal from synthetic sample was found to be 92.5 % for the contact time 6 hrs. The adsorption equilibrium data fitted well to Freundlich isotherm than Langmuir
