摘要
通过改进原分析方法的泡沫塑料预处理、吸附、洗涤、灰化和装样 5个步骤 ,可以有效地简化原分析方法的分析流程 ,缩短分析周期 ,减小劳动强度 ,降低生产成本 ,从而提高分析测定方法的灵敏度和准确度 ,方法改进后金的最低检出限可达 0 .1ng/g。
By improving the five processes of chemical analysis with foam-pretreatment,adsorption,washing,cinefaction and loading,the analyzed procedure is simplified,the analyzed cycle is shortened,the working intensity is decreased,and the cost is decreased.Further more,the sensitivity and accuracy are improved,and the detection limit of trace gold using this method can be up to 0.1ng per gram.
