本文提供了一个用火焰原子吸收法测定包容模拟核素Cs、Sr固体浸出液中Cs、Sr的连续测定方法。对一些主要共存元素Si、Fe、Al、Ca、Mg、K、Na对Cs、Sr测量的干扰,以及干扰的消除进行了某些研究。加入1.00mg/mlK+作为消电离剂,2.50mg/ml La~(3+)作为释放剂,在同一溶液中进行Cs、Sr连续测定。测得本方法回收率Cs为96％,Sr为98％。本方法简便易行,能为放射性废物固化试验迅速准确地提供分析数据。并能适用于水泥以及玻璃固化体中核素Sr、Cs的测定。 This article provides a continuous flame atomic absorption spectrometry determination of Cs, Sr solid leaching solution containing simulated nuclides continuous determination. Some studies have been conducted on the interferences of Cs, Sr and Si, Fe, Al, Ca, Mg, K, Na measured by some major coexisting elements. Adding 1.00mg / ml K + as deionizing agent and 2.50mg / ml La ~ (3+) as releasing agent, continuous determination of Cs and Sr in the same solution was carried out. The recovery of this method was measured Cs Cs 96%, Sr 98%. The method is simple and easy to provide analytical data for radioactive waste curing tests quickly and accurately. And can be applied to the determination of radionuclides Sr and Cs in cement and glass solidified body.
