摘要
采用连续法研究了3种矿物材料对Sr2+的吸附性能。试验结果表明,4A沸石对Sr2+的平衡吸附量为218 mg/g,沸石对Sr2+的平衡吸附量为24 mg/g,凹凸棒石对Sr2+的平衡吸附量为31 mg/g;单位质量4A沸石处理0.005 mol/L Sr2+溶液的能力最强,凹凸棒石次之,沸石稍次于凹凸棒石;4A沸石对Sr2+的阻滞效果最好,沸石次之,凹凸棒石最差。Sr2+在沸石柱中的迁移速率最小,其次是4A沸石柱,再其次是凹凸棒石柱。
Three mineral materials' adsorption capacity for nuclide Sr^2 + was studied by continuum method. The test results showed that the equilibrium adsorption amount of Sr^2+ in 4A zeolite was 218 mg/g; in zeolite 24 mg/g; and in attapulgite, 31 mg/g. Unit mass of 4A zeolite had the strongest capacity of treating 0.005 mol/L Sr^2+ solution, followed by attapulgite and then zeolite which was slightly inferior to attapulgite in this respect. For the Sr^2 + retarding effect, 4A zeolite was the best, zeolite the second and attapulgite the worst. The Sr^2 + migration rate was the lowest in zeolite column, higher in 4A zeolite column and the highest in attapulgite column.
