In this work, four different types of soils from Northwest of Sichuan were collected to study the influences of soil organic matter (SOM), depth of soil and the soil agglomerates structure on the sorption of biphenol A (BPA) on these materials which were peat soil (PS), non-sandified soil (ND), lightly sandified soil (LD), middle level sandified soil (MD) respectively. The study showed that the sorption kinetics of biphenol A on all four types of soils was fitted well with two-compartment first order kinetic model (R²≥0.98). And their sorption isotherms were fitted satisfactorily with both Freundlich and Langmuir models (R²≥0.98). The results revealed an obvious non-linearity sorption process (N, 0.52~0.70). When the soil was sandified, the degree of non-linear sorption increased, and the maximum sorption were dropped 3.5~5.7 times. The maximum sorption capacity (Q_m) of BPA on the four studied soils were 8901(PS), 7011(ND), 1506 (LD) and 1050 mg/kg (MD), respectively. The coefficient of correlation between Q_m and SOM in the soils samples was remarkably high (r > 0.999, P < 0.01). As the soil goes depth, the Q_m decreased remarkably in following order:MD > LD > ND > PS. With the increase of agglomeration of soil, the sorption capacity increased first, then decreased. The sandification made the sorption capacity remarkably different, therefore the contribution in sorption process varies greatly. The sorption contribution level of BPA was basically the same with five different sizes of agglomerates of non-sandified soil, whereas for the sandified soils LD and MD, the sorption of BPA was mainly contributed by the smaller agglomerates, with a 86%~88% contribution.
