The adsorption property of Cs by the three mineral materials was researched using continuum method,it offered some references for evaluating the disposition effect of mid-lower radwaste.The experiments showed that the equilibrium adsorption amount of Cs by 4A zeolite was 271 mg/g,the equilibrium adsorption amount of Cs by zeolite was 195 mg/g,the equilibrium adsorption amount of Cs by palygorskite was 22 mg/g;and the disposed capacity of 4A zeolite of unit quantity to Cs solution with the content of 0.005 mol/L was best;zeolite was on the small side than 4A zeolite;palygorskite was weakest;and the block effect of 4A zeolite on Cs was best;zeolite was on the small side than 4A zeolite;palygorskite was weakest;and transference velocity of Cs was least in zeolite column;the second was in palygorskite column;the last was in 4A zeolite column.
