This study reports on the adsorption reactions of trivalent antimony (Sb(Ⅲ)) and pentavalent antimony (Sb(Ⅴ)) on four adsorbents: ferric hydroxide, aluminum hydroxide, kaolin and vermiculite, which were used to simulate the main minerals in the soil. The results showed that the adsorptions of both Sb(Ⅲ) and Sb(Ⅴ) on the four adsorbents gradually become stable after 24 h. In addition, the adsorption of Sb(III) on vermiculite and ferric hydroxide reached to peak value at 6 h and then decreased. For example, the adsorption of Sb(Ⅲ) on ferric hydroxide was 23.19 μg/g at 6 h, and decreased to 19.75 μg/g at 72 h. The decline of adsorption and the increase concentration of Sb(Ⅴ) determined in supernatant indicated the oxidation of Sb(Ⅲ) during the adsorption process. The isothermal adsorption curves of two valence antimony were fitted well by Langmuir and Freundlich adsorption models, and the goodness of fit (R2) of both models were above 0.7. Comparing the fitting curve and the parameters obtained, the best adsorption of Sb(III) were shown on vermiculite and ferric hydroxide, while the absorbability of vermiculite to Sb(Ⅴ) was weak. Sb(V) were adsorbed better by ferric hydroxide and aluminum hydroxide, but aluminum hydroxide showed poor adsorption effect of Sb(III). Both valence antimony had anion adsorption characteristics, for the adsorption decreased while the desorption increased with the increase of equilibrium solution pH. For instance, the adsorption of Sb(Ⅲ) on kaolin increased from 10.12 μg/g to 37.89 μg/g when the equilibrium solution pH decreased from 4.82 to 2.12.
