中文摘要: 用HCl-HNO3混和酸溶解金精矿样品,用电感耦合等离子体发射光谱法(ICP-OES)测定。在选定的操作条件下,砷的检出限0.018μg/mL。相对标准偏差( n=11),RSD<2%,加标回收率在98.2%-103.0%之间。用该法测定金精矿中砷元素的含量,操作简单易行,能够满足日常生产需要。

Abstract:The gold concentrate samples were dissolved with HCl-HNO3 mixed acid and determined by ICP-OES. Under the selected operating conditions, the detection limit of arsenic is 0.018μg/mL. The relative standard deviation (n =11) was less than 2% RSD and the recovery was between 98.2 % and 103.0%. Using this method to determine arsenic content in gold concentrate is easy to operate and can meet daily production needs.
