不同产地石膏品质的探讨

Discussion of the Different Quality of Gypsum

目的:对不同产地石膏进行文献考证、资源考察、鉴别、含量测定,为探讨石膏的分级方法和建立与国际接轨的综合质量评价体系做基础研究。方法:广泛收集文献,调研资源概况,进行性状鉴别和化学鉴别,采用EDTA滴定法和行原子发射光谱对各个产地石膏样品进行含水硫酸钠含量和微量元素Gu、Mn、Sr、Zn、Fe含量测定。结果:湖北应城的石膏形状上更符合传统石膏鉴别的优等特征,样品中二水合硫酸钙含量在99%以上,含水硫酸钠和微量元素含量高于其他产地石膏样品。结论:综合文章所得数据,湖北应城石膏品质最好。

Objective ： To study the different gypsum resources, literature research, identification, content determination, classifi- cation for gypsum and the establishment of the comprehensive quality evaluation system in line with international standards. Meth- ods ：The extensive collection of literature, research resources, character identification and chemical identification was made by u- sing the origin of gypsum samples were sodium sulfate content of aqueous and trace elements Gu, Mn, Sr, Zn, Fe content EDTA tit- rimetric method and atomic emission spectrometry. Results ：The shape of the gypsum Hubei Yingcheng more in line with the excel- lent characteristics of traditional gypsum identification, content of two hydrated calcium sulfate samples in 99% above, aqueous so- dium sulfate and trace element content was higher than other areas of gypsum samples. Conclusion： The data from the Huhei Yingeheng gypsum has the best quality.
