The sorption properties of cesium in the soil of a nuclear waste repository were investigated by column method. The effects of pH value, granularity of the soil, concentration of cesium solution on the sorption properties were also studied. The experiment results show that the equilibrium adsorptive quantity increases with the increasing of pH value and the initial concentration of cesium solution and decreases with the increasing of the grain size of the soil. This has no orderliness between equilibrium adsorptive quantity and pH value, the grain size of the soil. The most sorption rate of cesium in the soil of the primary election nuclear waste disposal is 65.9%, and the sorption properties are not well. So, people must use something which can adsorb cesium well as a barrier before the disposition.
