不同产地石膏成分含量的比较分析

目的探讨不同产地石膏成分含量差异,为临床应用提供依据。方法选取十个产地石膏样品,采用乙二胺四乙酸二钠(EDTA-2Na)滴定法进行含水硫酸钙含量测定,分析不同产地及不同产区石膏含水硫酸钙含量。结果各产地石膏样品含水硫酸钙含量均超过95%,符合国家药典委员会制定《中华人民共和国药典》(2010年)测定要求;湖北荆门产区石膏样品含水硫酸钙含量平均值最高,以下依次为湖北应城产区、河北邢台及河南三门峡;其中湖北荆门产区又以磊鑫石膏有限公司提供样品含水硫酸钙含量最高,达到99.772%;而不同颜色石膏中白色石膏含水硫酸钙含量最高,以下依次为红色石膏、透明石膏,蜡黄色石膏含量最低。结论各产区石膏含水硫酸钙含量均达到国家标准;湖北荆门地区石膏含水硫酸钙含量高于其他地区,其中尤以磊鑫石膏有限公司含量最高。

Comparative Analysis of Different Origin Plaster Ingredients

Objective To investigate the origin of the gypsum content between different components provide the basis for clinical application. MethodsTen origin plaster samples, aqueous sulfuric acid content was determined by calcium disodium edetate（EDTA-2Na） titration analysis of different origin and different areas of gypsum calcium sulfate water content. Results The Origin of gypsum calcium sulfate content of water samples exceeded 95%, in line with the National Pharmacopoeia Committee to develop ＂Chinese Pharmacopoeia＂（2010） Determination of requirements; Hubei Jingmen producing gypsum calcium sulfate content of the sample average of the highest water content, the following order of producing city of Hubei Province, Xingtai, Hebei and Henan Sanmenxia; areas where Jingmen Youyi Leixin gypsum Company provides the highest sample moisture content of calcium sulfate, reaching 99.772%; while the highest calcium in different colors white gypsum plaster aqueous sulfuric acid content, the following followed by red plaster, transparent plaster, wax yellow plaster lowest levels. Conclusion Each producing gypsum calcium sulfate content of water met the national standard; calcium sulfate gypsum moisture content of Jingmen areas than other regions, especially in the highest levels Leixin Gypsum Co.;.
