The sorption and desorption kinetics of dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP) and phenol on water and sediment interface were studied using two-compartment model in this paper. The results showed that the sorption coefficients of DMP, DEP, DBP and phenol measured by batch equilibrium method were 16.79, 24.55, 132 and 0.65 mu g super(1-1/n)/g /ml super(-1/n), the sorption and desorption kinetic constants of DMP, DEP, DBP, phenol were 0.0248, 0.0357, 0.0727, 0.014 ml/cm super(2)/h and 0.000512, 0.000754, 0.00127, 0.000899 h super(-1) at static condition respectively; and the sorption and desorption kinetics constants of above chemicals were 0.279, 0.382, 0.496, 0.0904 ml/cm super(2)/h and 0.0442, 0.0031, 0.00116, 0.00247 h super(-1) at flow water condition respectively.
