また、鉄酸塩は、強い酸化力を有することがら、一般的
に酸化剤として使用することができ。In addition, ferrates have strong oxidizing power and can generally be used as oxidizing agents.
その酸化力を生かして消毒剤としても使用できる。It can also be used as a disinfectant due to its oxidizing power.
しかしながら、鉄酸塩は分解しゃすく長期にわたって安

■加水分解は高次反応であるから低濃度にすると安定化
に向かうが、実用レベル濃度の安定化は得られない。■Hydrolysis is a higher-order reaction, so lowering the concentration tends to stabilize it, but it does not stabilize the concentration at a practical level.
■鉄酸塩の分解は、酸・塩基触媒反応であり。■Decomposition of ferrate is an acid/base catalyzed reaction.
非常に狭い範囲にＰＨ安定域はあるものの、安定化の程
度実用には適しない。Although there is a pH stability range within a very narrow range, the degree of stabilization is not suitable for practical use.
■鉄酸はカチオンを中心原子として結合する如き多分子
結合構造をとるようであり、しかもカチオンとしてプロ
トンを介在した結合よりも多価カチオンを介在させた方
が強く結合する。(2) Ferric acid seems to have a multimolecular bond structure in which it bonds with a cation as the central atom, and moreover, the bond is stronger when a polyvalent cation is involved than when a proton is involved as a cation.
