本文用微量取样雾化火焰原子吸收分析技术测定了土壤中的银。结果表明:本方法可直接用于测定土壤中微量银。分析灵敏度为0.04ppm。与常规法相比,绝对灵敏度可提高10倍。回收率为95％—116％,样品分析的相对误差为5.5％。 In this paper, micro-sampling atomization flame atomic absorption spectrometry was used to determine the silver in soils. The results show that this method can be directly applied to the determination of trace silver in soil. Analysis sensitivity of 0.04ppm. Compared with the conventional method, the absolute sensitivity can be increased by 10 times. The recoveries ranged from 95% to 116% with a relative error of 5.5% for sample analysis.
