锍镍试金-等离子体质谱法测定地球化学勘探样品中的铂族元素和金Ⅱ．分析流程空白的降低

Determination of Platinum Group Elements and Gold in Geochemical ExplorationSamples by Nickel Sulfide Fire Assay-ICPMS

摘要: 对锍镍试金富集－等离子体质谱法测定贵金属流程中的试剂空白进行了检查，并对空白主要来源－捕集剂镍的各种纯化方法作了对比，提出了回收试金流程中溶扣后滤液中的镍循环使用。在有效降低空白的基础上，满足了化探样品所要求的0.0x ng/g级检出限，对超痕量贵金属标样分析结果与标准值符合。
