原子荧光光谱法测定地质化探样品中的锗

Determination of germanium in geological geochemical samples by atomic fluorescence spectrometry

本文利用原子荧光光度法测定地质化探样品中的锗,对影响锗的灵敏度测定的因素进行了较为系统的试验分析。通过了磷酸介质的酸度、原子化器高度、灯电流、KHB4浓度、载气流量等条件因素的比较确定了最佳的测定条件,取得了满意的测定结果。

This paper makes a systematic test and analysis on the factors that affect the sensitivity of the sample by atomic fluorescence spectrometry. The optimum conditions were determined by the comparison of the acidity of the phosphoric acid medium, the height of the atomizer, the lamp current, the concentration of KHB4 and the flow of the carrier gas. The satisfactory results were obtained.
