摘要
Abstract
This study developed an analytical method for the determination of uranium and molybdenum in raffinate wastewater from ura-nium-molybdenum extraction and metallurgy using energy dispersive X-ray fluorescence spectrometry(EDXRF).By optimizing the spectrometer working conditions(50 kV,600 μA),calibration curves between concentration and fluorescence intensity were estab-lished for uranium(1~10 μg/mL)and molybdenum(5~40 μg/mL),with linear correlation coefficients of 0.998 and 0.999,respectively.The method's reliability was verified through spike recovery tests and repeatability tests on actual samples.Spike recovery rates ranged from 97.3%to 104.0%and the precision,expressed as relative standard deviation(RSD),was better than 2%for Mo and8%for U(n=11).The proposed method is characterized by simple operation,rapid analysis,and no requirement for complex sample pretreatment,making it highly suitable for on-site rapid monitoring of raffinate wastewater.关键词
