摘　　要：银是一种极为贵重的贵金属元素,无论是在人们的日常生活中,还是在工业生产中,它的用途均是极为广泛的。正因如此,科学、合理、有效的从岩石、土壤以及其他物质中提取微量银是极具必要性的。据统计,当前微量银的测定方法极多,如分光光度法、电化学分析法、化学发光法、荧光光谱法、原子吸收分光光度法、发射光谱法等都是目前微量银测定时使用频率较高的方法。值得注意的是,与上述这些测定方法相比,火焰原子吸收法更简便、快捷、成本低、准确性高,因此在岩石、土壤中进行微量银测定时使用频率较高。借此,本文就火焰原子吸收法在微量银测定方面的具体情况进行试验分析,报道如下所述:Silver is an extremely valuable precious metal element,both in peopleundefineds daily life and in industrial production,its use is extremely extensive.For this reason,scientific,rational,and efficient extraction of trace silver from rocks,soils,and other substances is essential.According to statistics,there are many methods for the determination of trace silver,such as spectrophotometry,electrochemical analysis,chemiluminescence,fluorescence spectrometry,atomic absorption spectrophotometry,Emission spectrometry is a high frequency method for the determination of trace silver.It is worth noting that compared with these methods,flame atomic absorption spectrometry is simpler,faster,lower cost and higher accuracy,so the use frequency of trace silver in rock and soil is higher.In this paper,the specific conditions of flame atomic absorption spectrometry in the determination of trace silver are analyzed.The results are as follows.
