Solid waste management is one of the most significant problems the Indian government is trying to deal with. In the last two decades, India has witnessed tremendous growth in social and economic sectors. An intensive study has been made to see the performance of the bentonite on the removal efficiency of Heavy Metal from the landfill. A stock solution of 100 mg/litre of lead was prepared by dissolving 1.6 g Pb(NO3) in 1 L deionized water. Metal solution of required lower concentration was prepared by diluting the of stock solution. The volume of sample was determined to be 1 litre. pH adjustment for this study was carried out using 0.1 N HCl and 0.l N NaOH. The amount of clay is taken in the range of 5 g to 15 g. The mixture of clay and metal solution was stirred for 2 hours at 200 pm on magnetic stirrer. Centrifuge was used to separate the clay from the solution. The concentration of lead remains in solution after adsorption was analysed in the Spectrophotometer. In this study, the effect of parameters like pH value, metal concentration, amount of clay, agitation time and speed were examined. The optimal experimental conditions for maximum lead removal was achieved at 0.9 g/L of bentonite clay and solution pH of 10.5. An increase in concentration more than 20 mg/l shows the decrease in percentage of adsorption. It has been observed that maximum adsorption occurs in within 30 minutes. Therefore, it can be said that adsorption is a spontaneous phenomenon. The experimental work proved that the Bentonite clay will be the best option for the removal of heavy metal from the landfill.
