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。A method was established by polarized radiation-energy dispersive X-ray fluorescence spectrometry to determine six metal elements simultaneously. The test Parameters 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 test results of the soil standard samples met the requirement. The RSD of practical samples were from 0.5% to 10.0% , and equaled to resuhs of AAS, AFS tests
