Kinetic Study of COD in Coking Wastewater on Lignite Activated Carbon

摘要：

　　The adsorption kinetics and adsorption mechanism of the activated carbon on COD were studied.The reaction kinetics of lignite activated carbon at different temperatures is verified by pseudo first order reaction and pseudo second-order reaction model, and the rate constants of these dynamics models are fitted.The results showed that the adsorption can be expressed by the pseudo-second-order model, the equilibrium adsorption is 50.8mg/g at 98K temperature, the adsorption process is the exothermic process.Finally, the activation energy of the adsorption process is calculated as 5.76kJ/mol, and the adsorption process is physical adsorption.
