| 摘 要： | 通过电感耦合等离子体质谱法测定化探样品中As的分析方法,利用1:1王水在沸水浴中溶矿,用ICP-MS直接测定。方法的检出限为0.0113μg/g,精密度RSD%小于3%,用国家标准物质验证的结果与标准值一致。方法简便快速,适合应用于大批量化探样品中As的测定。

DETERMINATION OF TRACE ARSENIC IN GEOCHEMICAL EXPLORATION SAMPLES BY INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY |
| |
| Abstract: | Determination of arsenic in geochemical exploration sample is analyzed by inductively coupled plasma mass spectrometry, which using the 1:1 aqua regia dissolving ore in a boiling water bath. Detection limit of this method is 0.0113 mu g/g, precision RSD % is less than 3%, and the verification results of the national standard material is consistent with the standard values. This method is simple and rapid, and suitable for application in large quantities of the determination of arsenic in geochemical samples. |
