摘要
讨论了化探样品中金测定过程中的分解方法、金的富集、酸度及流速、泡塑清洗及控制等条件,严格控制各个分析环节,通过对标准样品进行分析,相对标准偏差为0.75%—3.64%,回收率为95.0%—105.0%,方法适合批量样品生产,能达到化探样品中金含量的分析要求。
Decomposition method, the enrichment, acidity and flow rate, foam cleaning and control conditions for the determination of gold in geochemical samples were discussed. All aspects of the analysis was strictly controlled, through analysis of standard samples, the relative standard deviation was 0. 75%-3. 64%,the recovery was 95.0%--105. 0%. The method is suitable for the production of bulk samples ,and can achieve the need of the sample analysis.
