摘要
Abstract
Objective To establish a spectrophotometric method for the determination of ferrous iron in ferric chloride hexahydrate. Methods The detection methods on ferrous iron in ferric chloride hexahydrate among European Pharmacopoeia,United States Pharma-copoeia and Chemical Reagent Ferric Chloride Hexahydrate(HG/T3474-2014)of China's Chemical Industry were compared. The last two methods were not easy to operation. On the basis of the European Pharmacopoeia,a method was proposed that after Fe3+ were screened with H3PO4,Fe2+ was measured by spectrophotometry,and the method was verified by experiments. Results and Conclusion The spectrophotometry method is easy to operate and has good reproducibility.关键词
