摘要
研究了微量铁( Ⅲ) 在盐酸介质中催化邻苯二胺的聚合反应及其最佳实验条件,建立了测定微量铁( Ⅲ) 的新方法- 方法的ε= 3 .689 ×103L·moL- 1·cm - 1 ,检测范围为0 ~100 mg/25 mL,用于测定食品中的微量铁( Ⅲ) ,获得了满意结果-
This paper has studied the polymerized reaction of o-phenylenediamine based on the catalysis of trace Fe(Ⅲ) in hydrochloric acid and its optimunm experimental corditions.A new determination meltcod for trare Fe(Ⅲ) is established.ε is 3.689×10 3 L·mol -1 ·cm -1 ,the range of determination is from o to 100 μg/25 mL.It is applized satisfactorily to the determination of trace Fe(Ⅲ) in several food samplec.
