Objective: To optimize processing technology of Natrii Sulfas. Method: With the content of magnesium ion in Natrii Sulfas as index
orthogonal test was adopted to optimize processing technology by taking radish addition
water addition and processing time as factors.The content of magnesium ion was determined by atomic absorption spectrophotometry with detection wavelength of 285.28 nm.The content of sodium sulfate in different processed products was measured. Result: The best processing technology was as following:added 5 times the amount of water and 0.1 times the amount of radish for processing 1 hour.Contents of magnesium ion and sodium sulfate were 7.143 μg·g-1 and 97.83%
respectively. Conclusion: This optimized processing technology is stable and feasible
it is significant to regulate processing technology of Natrii Sulfas
this paper shows that Natrii Sulfas processed by radish is rational.
