%X The adsorption equilibriums of Methyl Parathion (MP) and Trichloroethylene (TCE) onto three kinds of powdered activated carbons (PAC) in a natural water were studied using batch tests, and the homogeneous surface diffusion model (HSDM) was applied to fit and predict adsorption kinetics at different PAC doses. The competitive adsorption of natural organic matter (NOM) with MP and TCE on PAC was discussed. Both Langmuir and Freundlich isotherms fitted well to the adsorption of MP and TCE on three kinds of PAC. The adsorption capacities of three kinds of PAC were in the order of YK>SL>JC, while the adsorption for MP was higher than that for TCE. The adsorption kinetics were well fitted by HSDM model, and the adsorption kinetics at different PAC doses could be predicted effectively using HSDM. NOM exhibited competitive adsorption effect with MP and TCE. The competitive adsorption effect of NOM with MP was stronger than that with TCE.
