化学光谱法测定化探样品中痕量金

High-speed determination of trace gold in geochemical sample by chemi-spectrophotometric method

拟定了化探样品中痕量金的快速、简便、灵敏度高的化学光谱分析方法 ,特别适合大批量化探样品的分析 ,一次摄谱的测定范围为 (0 0 3～ 5 0 0 0 )× 10 - 9。

A chemi-spectrophotometric method was drawn up for the determination of trace gold in geochemical sample.Being a quick,simple,and high-sensitive method,it was suitable for the analysis of large-batch of geochemical sample.The determination range of spectrographic analysis is (0.03～5 000)×10 -9
