摘要
在紫外光照射下，很多有机物质和部分无机物质能够发出不同颜色和亮度的荧光。本文研究了含油岩芯中岩石矿物的荧光特征，指出采用氯仿（或乙烷）试剂浸泡岩样是区别岩石矿物荧光的有效方法。本文着重对含油岩芯中有机质组成以及有机组分与荧光颜色的关系进行了深入的探讨，指出依据含油岩芯的荧光颜色可以进行油气水层的荧光解释。
Trace gold in geological samples were on line preconcentraced with diphenylthiourea cotton cellulose prepared in our laboratory,and determined by FI FAAS.Under this special condition,the determined vellocity is 30 samples/h;the determined sensitivity is 0.31 μg/ml(1% absorption);the RSD is ±2.59%.
