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.
