中文摘要:
      采用粉末压片法制样,利用理学ZSX PrimusⅡX射线荧光光谱仪,用国家标准物质土壤(GSS系列)、沉积物(GSD系列)、环境保护部标准样品研究所研制的土壤标准样品GSB Z 50011-88(黑钙土)、GSB Z 50012-88(棕壤)、GSB Z 50013-88(红壤)、GSB Z 50014-88(褐土)、湖南污染土壤标准(GBW0732729)做标准样品,建立XRF方法测定农业地质土壤污染物样品中的Cu、Pb、Cr、Ni、Zn、Co、As、Mn、V这9种重金属元素的方法,采用经验系数法校正谱线重叠干扰和基体校正。用3个土壤考核样和环境保护部标准样品研究所研制的GSB07-3272-2015作为样品评估该方法的准确度和精密度,结果符合《全国土壤污染状况详查土壤样品分析测试方法技术规定》中上述元素的规定检测方法质量要求。
英文摘要:
      Soil standard samples GSB Z 50011-88 (black calcareous soil), GSB Z 50012-88 (brown soil), GSB Z 50013-88 (red soil), GSB Z 50014-88 (cinnamon soil) developed by National Standard Soil (GSS series), Sediment (GSD series) and Institute of Standard Samples of Ministry of Environmental Protection (Institute of Standard Samples) were prepared by powder pressing method and ZSX Primus II X-ray fluorescence spectrometer. The dyed soil standard (GBW0732729) was used as the standard sample to establish an XRF method for the determination of nine heavy metal elements, namely, Cu, Pb, Cr, Ni, Zn, Co, As, Mn and V, in agricultural geological soil pollutant samples. Empirical coefficient method was used to correct overlapping interference of spectral lines and matrix correction. GSB07-3272-2015, developed by the Institute of Standard Samples of the Ministry of Environmental Protection, was used as a sample to evaluate the accuracy and precision of the method. The results met the quality requirements of the above-mentioned elements in the Technical Regulations for the Analysis and Testing of Soil Samples for the National Detailed Investigation of Soil Pollution.
