摘要
建立了用三氯化钛-重铬酸钾测定饲料级硫酸亚铁中的Fe(Ⅱ)和Fe(Ⅲ)的方法,讨论了各种反应条件对测量结果的影响;用已知的模拟标准样品测量,方法的加标回收率为98%-102%。方法准确可靠、简单实用,可用于饲料级硫酸亚铁中的Fe(Ⅱ)和Fe(Ⅲ)的测定。
A method for the determination of Fe( Ⅱ) and Fe(Ⅲ) in feeding ferrous sulfate was established. The influencing factors were discussed. Recoveries of the Fe( Ⅱ) and Fe(Ⅲ) were proved to be 98%-102% in spiked samples. This method is reliable and practicable to determine Fe( Ⅱ) and Fe(Ⅲ) in ferrous sulfate.
