Abstract：
This paper studies the quality control in determination of Ferrum content by sulfosalicylic acid spectrophotometry. Choose sulfosalicylic acid as chromophoric reagent and determine the Ferrum content in sample solution by working curve method, then discuss the best conditions for the determination. This method is simple and easy to operate, with less interference and low analysis cost. Its accuracy and precision meet the determination requirements and the result is satisfactory.
