锶特效树脂用于环境水样品中90Sr的富集、分离和测量方法研究

通过正交实验对影响阳离子树脂洗脱、锶特效树脂淋洗和洗脱的主要因素（酸度、流速、用量）进行了优化,结合阳离子树脂富集、锶特效树脂分离和α/β测量仪测量,建立了快速分析环境水样品中90Sr的方法。该方法对实际水样品中的锶进行分离及化学回收率测定,化学回收率均高于95%,表明该方法操作简单,分离流程短,工作效率高,可以得到稳定的化学回收率,适用于环境水样品中90Sr的富集和分离。采用锶特效树脂柱分离环境水样10次后,锶的化学回收率仍高于90%,具有较高的稳定性。...

The influence of parameters （acidity, flow rate and amount） of cationic resin elu- tion, Sr resin leaching and elution were optimized by ortho-experiment. Combined with the enrichment of cationic resin, the separation of Sr specific resin and the measurement of α/β instrument, a rapid analysis method of 90Sr was established in environmental water. The chemical recoveries are over 95% when the method was used to actual water, indicating that this method is simple, short and efficiency, can provide stable chemical recovery, is suitable for enrichment and separation of 90 Sr in environmental water. When the Sr specific resin col- umn was used in environmental water after 10 times, the chemical recovery rate of Sr is still higher than 90%. The resin has high stability.
