    摘要:

    因U-Zr合金的優(yōu)良性能，未來將會受到越來越廣泛的應(yīng)用，為滿足大量U-Zr合金常規(guī)分析的需求，本文研究了用能量色散X射線熒光光譜(EDXRF)法測定U-Zr合金中Zr的含量。切削樣品經(jīng)溶解、轉(zhuǎn)移、烘干等操作后，制備出薄層樣品，用EDXRF來測量。與傳統(tǒng)方法相比，本方法簡便、快速、準(zhǔn)確，適用于Zr含量在6%～18%范圍的U-Zr合金樣品的Zr含量測定，測量結(jié)果的相對標(biāo)準(zhǔn)偏差(n=6)不大于1.0%，方法擴(kuò)展不確定度(k=2)不大于3%。

    Abstract:

    Because of excellent properties, U - Zr alloy will be used widely more and more in the future. To meet the large amounts of U - Zr alloy routine analysis, Energy Dispersion X-ray Fluorescence was used to determine zirconium content in U-Zr alloy in the present study. The thin-layer samples were prepared through dissolution, transferring and drying. Compared to traditional methods, this method shares simplicity, rapidness, as well as accuracy. It can be used in the determination of Zr content in the range of 6%-18% in U-Zr alloy. The relative standard deviation (RSD) (n=6) is not above 1.0%. The extended-uncertainty (k=2) is not above 3%.
