石墨中36Cl分析的溶样技术
Dissolution of 36Cl in Graphite Sample
-
摘要: 在反应堆退役过程中,为了使放射性废物最小化,需对石墨中的36Cl进行分析。采用浓硫酸、浓硝酸和高锰酸钾的混合溶液溶解石墨样品,建立了石墨的溶样方法。该溶样方法对36Cl的化学回收率大于89.38%。Abstract: In order to minimize radioactive wastes, it is necessary to analyse 36Cl in graphite during reactor decommissioning. The dissolution method was set up. The mixed solution of H2SO4, HNO3 and KMnO4 was used to dissolute graphite samples. The chemical recovery rate of the dissolution method was more than 89.38%.
