摘　　要：目的:建立小儿清热止咳口服液中二水硫酸钙含量测定方法。方法:先将样品炭化后灰化,然后应用EDTA络合滴定法测定二水硫酸钙的含量。结果:3批不同的小儿清热止咳口服液中二水硫酸钙的质量浓度分别为1.033,2.172,1.872 g.L-1。平均回收率为97.35%,RSD 1.21%。结论:方法操作简便,可用于小儿清热止咳口服液中二水硫酸钙的含量测定。Objective：To establish the analysis method for content determination of calcium sulfate dihydrate in Xiao’er Qingre Zhike Koufuye. Method： Samples were charcoaled and incinerated to ash, and the content of calcium sulfate dihydrate was determined by complexometric titration. Result： The content of calcium sulphate dihydrate in three batches of Xiao’er Qingre Zhike Koufuye was 1.033, 2.172, 1.872 g·L-1 respectively. The average recovery was 97.35% with RSD of 1.21%. Conclusion：The method established was simple in operation, and can be used for the determination of calcium sulphate dihydrate in Xiao’er Qingre Zhike Koufuye.
