本文提出灼烧 -盐酸浸取预分离干扰元素 ,以盐酸、双氧水加入助溶剂 ( X- 1)分解样品 ,用分光光度法测定铂。线性范围 0～ 5.0 μg/ m L,相关系数为 0 .9996,加入标准回收率为 98%以上。
In this paper, the burning-hydrochloric acid pre-separation interference element leaching, hydrochloric acid, hydrogen peroxide added co-solvent (X-1) decomposition samples, spectrophotometric determination of platinum. The linear range was 0-5.0 μg / mL with a correlation coefficient of 0.9996. The standard recovery was over 98%.
