摘　　要：为便于无水硝的生产控制及产品质量分析,参照国家标准方法,寻找一种快速、简便的硫酸根(SO42-)含量测定方法-以氯化钡为沉淀剂,以阿拉伯胶做保护剂的分光光度法。In order to facilitate the production control and product quality analysis of anhydrous sodium sulfate,a fast and simple determination method of SO 42- content-spectrophotometry is found based on the na-tional standard method in which barium chloride is used as precipitating agent and Arabian gum is used as protective agent.
