两种不同来源的矿物药石膏矿物学分析及鉴定

Mineralogical analysis and identification of two different sources of mineral medicine gypsum

目的从矿物学角度,对陕西省矿物药石膏产地西乡县及陕西省药材公司两种不同来源的石膏矿物药进行系列测试分析及鉴定,以确定是否符合入药条件。方法肉眼鉴定矿物学特征、X射线衍射、红外光谱、差热分析等进行了对比测试,并综合前人X射线粉晶数据,对其进行化学分析及光谱半定量分析。结果 2种不同来源的矿物药石膏矿物学特征相似,陕西省西乡县所产矿物药石膏符合入药条件。结论经对比,笔者认为陕西省西乡县产出的石膏符合矿物药开发标准,可作为矿物药资源进行开采。

Objective From the viewpoint of mineralogy, a series of test analysis and identification of Shaanxi province mineral medicine gypsum production in Xixiang county and Shaanxi Province medicine company from two kinds of gypsum mineral drug, to determine compliance with the conditions. Methods The mineralogical characteristics of naked eye were characterized by X-ray diffraction, infrared spectrum and differential thermal analysis. The X-ray powder crystal data were analyzed by chemical analysis and semi-quantitative analysis. Results The mineralogical characteristics of two kinds of mineral medicine gypsum were similar, and the mineral medicine gypsum produced in Shaanxi County of Xixiang province was in accordance with the medical conditions. Conclusion Through comparison, the author believes that the gypsum produced in Shaanxi County of Xixiang province conforms to the mineral drug development standard and can be used as mineral medicine resources for exploitation.
