| 摘 要： | 本文采用连续法研究了沸石及凹凸棒石矿物对Cs 的吸附性能,为评价中低放核废物处置效果提供一些参考依据。实验表明:4A沸石对Cs 的平衡吸附量为271mg/g,沸石对Cs 的平衡吸附量为195mg/g,凹凸棒石对Cs 的平衡吸附量为22mg/g;单位质量4A沸石处理0.005mol/L Cs 溶液的能力最强,沸石稍次于4A沸石,凹凸棒石最弱;4A沸石对Cs 的阻滞效果最好,沸石略次之,凹凸棒石最差。 |

| Abstract: | 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. |
