| 摘 要： | 采用连续法研究了沸石及凹凸棒石矿物对Cs+的吸附性能,目的是为中低放核废物的安全处置提供参考依据。结果表明: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: | In this article,the adsorption capacity of three mineral materials for nuclide Cs~ was studied aimed primarily to offer some reference for appraising mid-and low radwaste disposal.Experimental results showed that the equilibrium adsorption amount of Cs was 271mg/g in the 4A zeolite,the equilibrium adsorption amount of Cs was 195mg/g in the zeolite,the equilibrium adsorption amount of Cs was 22mg/g in the palygorskite;and the disposal capacity of 665mg/L solution of Cs by 4A zeolite of unit quantity is best;zeolite is inferior to the 4A zeolite,the palygorskite is weakest;and the retardation effect of Cs is best in the 4A zeolite,zeolite is inferior to the 4A zeolite;the palygorskite is weakest. |
