摘    要:
目的建立南寒水石的质量标准。方法采用化学鉴别法进行南寒水石的钙盐和碳酸盐的鉴别反应;采用乙二胺四乙酸二钠配位滴定法测定南寒水石中碳酸钙(CaCO3)的含量。结果所收集的南寒水石均符合碳酸盐和钙盐的鉴别反应,乙二胺四乙酸二钠配位滴定法测定南寒水石中碳酸钙(CaCO3)含量的方法,重现性好(RSD=0.34%),碳酸钙在0.06~0.30 g线性关系良好(r=1.000),平均回收率(n=9)为98.3%,RSD=0.4%。12批样品CaCO3含量的平均值为98.6%。结论所建立的南寒水石化学鉴别和定量测定方法简单准确,能够控制该矿物药的质量。 更多还原

关 键 词:乙二胺四乙酸二钠配位滴定法  南寒水石  碳酸钙

Abstract:
Objective To establish a quality control method for Nanhanshuishi.Methods Calcium salt and carbonate were detected by chemical identification,and the quantity of CaCO3 in Nanhanshuishi was determined by calcium disodium versenate coordination titration method.Results The method for the determination of CaCO3 in Nanhanshuishi had good reproducibility(RSD=0.34%).The calibration curve was linear(r= 1.000) within 0.06-0.30 g of CaCO3.The recovery was 98.3%(RSD=0.40%).Conclusion This method is convenient and accurate,which can be used to control the quality of the medicinal material.
Keywords:calcium disodium versenate coordination titration method; Nanhanshuishi; CaCO3;
