摘　　要：针对现行方法在地球化学样品金属元素分析中应用存在精准度、可靠度较低的问题,提出基于石墨炉原子吸收法与多光谱融合技术的地球化学样品金属元素分析。采用微波消解法对地球化学样品消解处理,利用石墨炉原子吸收法对样品原子化,融合多光谱技术对地球化学样品金属原子多光谱测定,分析金属元素含量,实现基于石墨炉原子吸收法与多光谱融合技术的地球化学样品金属元素分析。经实验证明,设计方法应用下所有金属元素分析值均在标准值范围内,并且加标回收率在95%以上,可以实现对地球化学样品金属元素精准可靠分析。In response to the low accuracy and reliability of current methods in the analysis of metal elements in geochemical samples,a metal element analysis of geochemical samples based on graphite furnace atomic absorption method and multispectral fusion technology is proposed.The microwave digestion method is used to digest geochemical samples,and the graphite furnace atomic absorption method is used to atomize the samples.The fusion of multispectral technology is used to determine the metal atom multispectral content of geochemical samples,and the metal element analysis of geochemical samples is achieved based on the fusion of graphite furnace atomic absorption method and multispectral technology.Experimental results showed that under the application of the design method,all metal element analysis values are within the standard range,and the spiked recovery rate is over 95%,which can achieve accurate and reliable analysis of metal elements in geochemical samples.
