利用显微傅里叶变换红外光谱仪原位分析铀矿物

Micro-area Analysis of Uranium Minerals by Micro FT-IR Spectrometry

利用显微傅里叶变换红外光谱仪分析技术,对下庄矿田338矿床矿石中的铀矿物进行了原位无损分析,避免了传统方法(KBr压片法)需要剂量大及纯度高的缺陷。实验表明:利用显微傅里叶变换红外光谱仪原位分析铀矿物是可行的,并且具有用量少(薄片面积大于20μm×20μm)及原位无损的特性,而利用显微傅里叶变换红外光谱仪的"MAPING"功能可以快速、大面积的鉴定不同矿物的接触关系,确定矿石的成分场特征。

The in-situ non-destructive inspection of micro Fourier transform infrared spectroscopy（Micro FT-IR） is used to analyze uranium minerals in NO. 338 uranium deposit of Xiazhuang ore field. The method avoids the disadvantages of high dosage and purity demands for the traditional method（KBr pressing disc method）. The research shows that in-situ analysis of uranium minerals by micro FT-IR spectrometry is feasible, and it has the characteristics of less sample（The sheet area must bigger than 20μm×20μm） and in situ non-destructive. The other function of Micro FT-IR Spectrometry is MAPING, which can identify the contact relationship of different minerals rapidly and large-scale, and determine the composition of minerals.
