| 摘 要： | 建立了偏振能量色散X射线荧光光谱同时测定土壤中6种金属元素的方法，优化了试验条件。方法线性良好，Cr、Mn、Pb、Cu、As、Se的检出限分别为3．62mg／kg、3．65mg／kg、0．91mg／kg、0．23mg／kg、0．35mg／kg、0．01mg／kg，土壤标准样品的测定结果均符合要求，实际样品测定的RSD为0．5％～10．0％，与原子吸收法、原子荧光法的测定结果相吻合。

| Abstract: | A method wasestablished bypolarized radiation -energy dispersive X-ray fluorescencespectrometryto determine six metalelementssimultaneously. The testparameters were optimized and good linearities were achieved. The detection limits of Cr, Mn, Pb, Cu, As, Se were 3. 62 mg/kg, 3. 65 mg/kg,0.91 mg/kg, 0.23 mg/kg, 0.35 mg/kg and 0.01 mg/kg separately. The testresultsofthe soilstandard samples metthe requirement. The RSD ofpracticalsamples were from 0.5% to 10.0% , and equaled to resultsofAAS, AFStests. |
