低浓度之亚鉄溶液用电流滴定法可获得滿意的結果。过去都用重鉻酸鉀作滴定剂。由于該氧化剂在反应中会形成不稳定的中間价态物貭Cr(Ⅴ)或Cr(Ⅳ),因此可引起一些有机物或无机物之誘导氧化。如用高铈作滴定剂則沒有这个缺点,因为高铈至亚铈之还原只包括一个电子,在此反应中不会形成能引起誘导反应之中間价态物貭,因此在亚鉄之滴定中高 Low concentration of 亚 鉄 solution with current titration method to obtain satisfactory results. In the past with potassium dichromate as a titrant. As the oxidant in the reaction will form an unstable intermediate valence 貭 Cr (Ⅴ) or Cr (Ⅳ), it can cause some organic or inorganic induced oxidation. Such as the use of high-titanate titration does not have this shortcoming, because the reduction of cerium to cerium only includes one electron, in the reaction will not form the intermediate valence inducing reaction 貭, so titration in the 鉄 亚High
