我国后处理厂产生的放射性有机废物长期存放后已变为粘稠胶状物。胶状物经初步处理,分为水相和有机相。利用石墨晶体预衍射X射线荧光仪,建立了测定处理后水相和有机相中U、Zr的分析方法。水相体系主要含有U、Zr等元素,但个别样品中Zr的含量很高,采用Ag散射内标法已不能校正Zr对 The radioactive organic waste produced by our reprocessing plant has become a viscous gum after long-term storage. After the initial treatment of jelly, divided into aqueous and organic phase. The analytical method of U, Zr in aqueous and organic phases after the determination of the treatment was established by using graphite crystal pre-diffraction X-ray fluorescence spectrometer. The aqueous system mainly contains U, Zr and other elements, but the content of Zr in individual samples is very high. The internal standard method of Ag scattering can not correct Zr
