摘要
建立了土壤样品中痕量银的石墨炉原子吸收光谱测定方法,优化了试验条件,标准曲线线性关系良好,当取样质量为0.25 g,定容体积为25 mL时,方法检出限为0.01 mg/kg。经标准样品验证,方法准确度符合土壤样品分析要求。
Method was established to determine the trace silver in the soils by graphite furnace atomic absorption spectrometry. The experimental condition was optimized. The liner relation of method was good. The limit detection of method was 0.01 mg/kg at preparing digestive solution 25 mL by weighing about 0.25 g of soil sample. The method meets the accuracy requirements for trace silver determination in the soils with confirmation of standard reference samples.
