摘要 采用自制的LⅢ吸收边分析装置，建立了测量20～200 g/L铀浓度的分析方法。通过实验确定了测量中铀的LⅢ吸收边左拟合区间为1659～1856道，右拟合区间为2063～2280道，铀的LⅢ吸收边为1995道。9 mol/L以下的硝酸、10 g/L以下的Al以及10 g/L以下的Fe对铀测量无显著影响。在铀的工作曲线范围内，其测量精密度均优于0.5％，稳定性好。利用本装置测量铀回收处理台架实验中的部分样品，取得了满意结果。 By independent research L Ⅲ-absorption edge densimeter ,an analytical method for uranium sample with the concentration from 20 g/L to 200 g/L was developed .The fitting area for uranium measurement was determined through experiment . The left fitting area was 1 659-1 856 channel ,and the right one was 2 063-2 280 channel .The uranium L Ⅲ-absorption edge was at 1 995 channel .The results show that the influence of HNO3 concentration lower than 9 mol/L ,Al and Fe concentration lower than 10 g/L was negligibly small .The uranium measurement precision is better than 0.5% ,and the instrument stability is good . Some samples in bench test of uranium recovery were determined .T he results are satisfactory .
