摘要
研究了改性凹凸棒石(CA)在不同环境条件下(浓度、温度、pH、介质)对模拟核素Cs+的吸附性能及其平衡吸附时间,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:CA对模拟核素Cs+的吸附性能受环境因素影响较大,在室温条件下,CA的吸附平衡时间为10天左右。CA吸附模拟核素Cs+后的晶胞体积总体增大,β角总体减小。
Thesis studied adsorptive equilibrium time and adsorption capacity of modified attupulgite （CA） on simulated nuclide Cs^＋ under a few conditions including temperature, pH value, concentration and medium with the intermittence method and offered some references for valuation of mid-lower radiative waste disposition. The experiment indicated that environmental factor severe effeeted adsorption capacity of CA on simulated nuclide Cs^＋ and adsorption equilibrium time of CA was about ten days under normal temperature. Unit cell volume of CA adsorbed simulated nuclide Cs^＋ increased, β angle decreased.
