چکیده
|
An attempt has been made to test the potential of hcl modified lagenaria siceraria (bottle gourd) peel (hlsp) towards cr6+ 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 cr6+ is 1.17 mg/g of hlsp. the adsorption of cr6+ by hlsp is well explained by different isotherms like ho & mc-kay equation (pseudo 2nd order kinetics),langmuir and morris-weber equation.
