摘要：An attempt has been made to test the potential of HCl modified Lagenaria siceraria (bottle gourd) peel (HLSP) towards Cr 6+ uptake. 120 minutes contact time and pH 4-5 is the optimum condition. Negative activation energy shows ease and exothermic nature of the adsorption process. The maximum uptake of Cr 6+ is 1.17 mg/g of HLSP. The adsorption of Cr 6+ by HLSP is well explained by different isotherms like Ho & Mc-Kay equation (Pseudo 2nd order kinetics), Langmuir and Morris-Weber equation.
