铋作为探途元素应用于化探工作[1,尤其在异常评价中具有重要意义。但铋的地壳丰度很低约为0．1ppm,用常规的化学分析和仪器分析方法灵敏度低,满足不了化探工作要求。本文在前人工作的基础上提出一个简单、快速、灵敏测定铋的氢化物发生无色散原子荧光分析法[2]①②。方法的检出 Bismuth is used as a journey element in geochemical exploration [1], which is of great significance especially in anomalous evaluation. However, bismuth has a very low crustal abundance of about 0.1 ppm, which can not meet the requirements of geochemical exploration using conventional chemical and instrumental analysis methods. Based on the previous work, this paper presents a simple, rapid and sensitive determination of bismuth hydride generation by atomic fluorescence spectrometry [2] ① ②. Method detection
