摘要
采用SbCl3氧化法合成的聚锑酸具有较好的机械性能,适合于色谱柱操作。聚锑酸在低酸度溶液中对锶吸附选择性好,在0.1mol/L硝酸溶液中对锶的吸附容量达到42mg/g。但是,聚锑酸对UO2+的吸附容量达到27.7mg/g。研究结果表明,聚锑酸只能用于不含铀废液中90Sr的去除。
The paper describes a new mothod for Polyantimonic Acid （PAA） synthesized and absorb capacticy of Sr^2＋ and UO2^2＋ on PAA. PAA synthesized by oxidation process with SbCl3 is with good mechanical strength and suitable for column operation. PAA has high affinity for Strontium in acid solution, and the adsorption capacity for Sr^2＋ is 42mg/g in 0.1 mol/L nitrate acid solution. But the adsorption capacity of UO2^2＋ on PAA is 27.7 mg/g. The results show that PAA can be used for ^90Sr removal from acid solution without UO2^2＋.
