STUDY ON ADSORPTION CAPACITY OF NUCLIDE Cs⁺ IN THE ZEOLITE AND PALYGORSKITE

Thesis studied adsorption capacity of nuclide Sr²⁺ in the three mineral materials with the continuum method and offered some references for valued mid-lower radwaste disposition.Experiments showed that equilibrium adsorption amount of Cs⁺ was 271mg/g in the 4A zeolite,equilibrium adsorption amount of Cs⁺ was 195mg/g in the zeolite,equilibrium adsorption amount of Cs⁺ was 22mg/g in the palygorskite;and disposed capacity of 0.005mol/L solution of Cs⁺ by 4A zeolite of unit quantity was best;zeolite was on the small side than 4A zeolite;palygorskite was weakest;and retardarce effect of Cs⁺ was best in 4A zeolite;zeolite was on the small side than 4A zeolite;palygorskite was weakest.
