摘要

[Objective]The research aimed to study the effect of underground temperature on the adsorption behavior of chlorobenzene under artificial recharge condition. [Method]Based on the prior researches,combining actual condition of the artificial recharge test site,the adsorption behavior of chlorobenzene under the background of artificial recharge was discussed. [Result]The adsorption reaction of chlorobenzene corresponded 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 chlorobenzene 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 artificial recharge was in summer.
