摘　　要：针对泡沫塑料吸附解析法应用情况进行讨论,以测定金含量为例,进行了简单的条件分析试验,对泡沫塑料吸附解析法测金的实验过程及关键步骤跟踪分析,并对影响泡沫塑料吸附解析法测金影响因素进行了探究,由实验结果表明在水浴时间40min,硫脲解析液浓度20g/L,解析液盐酸浓度为1%时,解析液对金的解析效果较好,并有效的提高了测金分析的稳定性。In this article,the foam adsorption analytic method application is discussed.Taking the determination of gold content as an example,the simple experiment of condition analysis is carried out,the experimental process and critical process of the foam adsorption analytic method to determinate gold content are analyzed,and the influencing factors which affecting foam adsorption gold analytical method test are explored.According to the experimental results,when the water bath time is 40 min,the thiourea analytical solution concentration is 20 g/L,and the hydrochloric acid concentration of the analytical solution is 1%,the analytical solution has a good analytical effect on gold,and the stability of gold analysis is improved effectively.
