摘    要:对X射线荧光(XRF)法检测土壤重金属的影响因素进行探讨,研究证实土壤样品厚度、粒径和含水率均会对荧光强度产生影响,且影响程度与X射线的能量有关,对低能量X射线的影响显著大于对高能量X射线的影响。为保障分析的质量,在应用XRF法进行土壤重金属检测时,土壤样品应完全干燥,混合均匀,保持土壤粒径均匀一致,土壤样品厚度统一为10 mm。

关 键 词:X射线荧光法  土壤  重金属

Abstract:This paper investigated factors that influence the XRF detection of heavy metals in soil.It was confirmed that the thick-ness, particle size, and water content of the soil sample would affect the fluorescence intensity to a various degree, which was de-pendent on the energy of X-rays.The results showed that low energy X-rays had significantly greater influence than high energy X-rays on the measurement.In order to ensure the quality analysis, soil samples should be completely dry, mixed evenly, maintained in uniform particle sizes and thickness of 10 mm when employing the XRF method for the determination of heavy metals in soil.
Keywords:XRF  Soil  Heavy metal
