摘要
Abstract
Objective To develop a ion chromatography assay for the determination of sodium sulfate in medicinal mirabilite. Method The Dionex ICS-3000 ion chromatograph equipped. IonPac? AS11 -HC column and Dionex ASR.S? 300 4-mm suppressor have been adopted, using NaOH solution(35 mmol/L) as eluent with a flow rate of 1.0 mL/min. Results The standard curve was linear in the range of 1.053-105.300 μg/mL for sodium sulfate with r of 0.999 7.The average recovery was 97. 1% and the RSD was 1. 2%. Conclusion The method is sensitive, accurate and operatable. And more stable than the assay method described in the Chinese Pharmacopeia. It is appropriate to the rapid control of quality for medicinal mirabilite.关键词
