摘　　要：验证了TEVA树脂作为萃取色层材料分离环境地表水中钚的效果。实验通过加标回收率、去污系数这两个指标评估了方法性能,更通过实验室间比对验证了方法的准确性和可靠性,并用此方法对5个不同点位环境水样中的钚进行了分析和测量。所有的实验结果均表明TEVA树脂能出色地分离出环境地表水中钚。In this paper,the effect of TEVA resin as extraction chromatographic material for separating plutonium from environmental surface water was verified.The performance of the method was evaluated by the recovery rate of standard addition and the decontamination coefficient.The accuracy and reliability of the method were verified by inter-laboratory comparison.Plutonium in water samples from five different locations was analyzed and measured by this method.All the experimental results show that TEVA resin can effectively separate plutonium from environmental surface water.
