摘　　要：提出了电感耦合等离子体原子发射光谱法(ICP-AES)测定阳离子交换树脂中15种金属元素含量的方法,优化了样品处理时灰化温度和ICP-AES测定条件,方法的检出限(3s)为0.2～210.0μg.L-1之间。分析了西安脉冲堆一回路系统将使用的新的和已使用的废阳离子交换树脂中15种金属元素含量,加标回收率在87.3%～102.2%范围内。利用所得结果,比较了新、废阳离子交换树脂中金属元素含量的差别,初步分析了西安脉冲堆一回路水系统中金属元素的来源。A method of ICP-AES for the determination of 15 metal elements in cation exchange resin was reported. The ashing temperature for sample treatment and working parameters of ICP-AES were optimized. The values of detection limits （3s） of 15 metal elements were in the range of 0. 2-210. 0 μg·L-1 The proposed method was applied to the analysis of new and used cation exchange resin from the primary water circulation system of the Xi＇an Pulse Reactor, giving values of recovery in the range of 87. 3%- 102. 2% Based on the analytical results obtained, a comparative study was made between the differences of contents of the metal elements in new and used cation exchange resin samples, and a preliminary deduction on the source of these elements in water samples of primary water circulation system of the Xiran Pulse Reactor was given.
