摘要
在模拟处置库条件下,采用北山地下水,用批式实验法研究了99Tc在内蒙古高庙子膨润土中的吸附行为,探讨了温度、pH值,添加剂黄铁矿(FeS2)、磁铁矿(Fe3O4)、方铅矿(PbS)、稀土赤铁矿(Fe2O3),以及CO32-、SO42-、Fe2+、Fe3+等对吸附行为的影响。研究结果表明,高庙子膨润土对99Tc具有一定的吸附阻滞能力,其吸附Kd值为98.4 mL/g。
The adsorption behavior of 99Tc in the bentonite was studied in anoxic conditions by batch method.The effect of temperature,pH value,pyrite,copper pyrite,galenite,hematite and the concentration of CO2-3,SO2-4,Fe2＋,Fe3＋ on the sorption behavior of 99Tc in the bentonite was studied.The results show that the Kd value of 99Tc in the bentonite is 98.4 mL/g.
