摘要 [ Objective] The research aimed to study the effect of underground temperature on the adsorption behavior of chlorobenzene under artifi- cial recharge condition. [ Method] Based on the prior researches, combining actual condition of the artificial recharge test site, the adsorption be- havior of chlorobenzene under the background of artificial recharge was discussed. [ Reset ] The adsorption reaction of chlorobenzene correspon- ded with quasi-first-order and quasi-second-order kinetics equations at certain concentration. When temperature rose, reaction rate accelerated, and adsorption balance time shortened to 12 （0 ℃）, 10 （10 ℃） and 8 （20 ℃） h. The adsorption of chlorobenzene corresponded with isothermal adsorption model very well at different concentrations. When temperature ranged from 0 to 20 ℃, the adsorption amount of medium on chloroben- zene increased at equilibrium time. The maximal adsorption amounts calculated by Langmuir model were 20.747, 21. 505, 23.364 μg/g at 0, 10 and 20 ℃, respectively. [ Conclusion] The adsorption of chlorobenzene in aquifer medium was endothermic reaction, and the best season of artifi- cial recharne was in summer.
