建立了一种基于扇形场ICP-MS和改进的阴离子交换分离钚的分析方法,用于沉积物和土壤样品中钚同位素的测定。铀的去污因子达到4 × 106,钚的化学产率提高到65%左右。通过对4种土壤和沉积物标准物质的分析验证了方法的有效性,分析结果与标准值和信息值吻合较好。并将该方法应用于实际沉积物和土壤样品中钚同位素的测定,以确定钚的来源。
An analytical method was established for the determination of plutonium isotopes in sediment and soil samples based on sector field ICP-MS and an improved anion-exchange procedure for Pu separation. A high U decontamination factor of 4 × 106was obtained and the chemical yield of Pu was improved to be about 65%. The developed method was validated by the analysis of four soil and sediment reference materials, the analytical results agreed well with the certified and information values. We further applied this method to determine Pu isotopes in actual sediment and soil core samples for Pu source identification.
