Fe( III )EDTA还原为Fe ( II )EDTA是湿法烟气系统同时脱硫和脱硝的核心过程。在此,首先,还原剂抗坏血酸(VC)用于还原Fe( III )EDTA。在不同的 Fe( III )EDTA 浓度、不同的 pH 值、不同的温度和不同的 VC 与 Fe( III )EDTA 的摩尔比下,研究了用抗坏血酸还原Fe( III )EDTA的可行性。结果表明,Fe( II )EDTA浓度随着初始Fe( III )EDTA浓度的增加而增加。此外,还原效率随着 VC 与 Fe 的摩尔比增加(III )EDTA增加,当摩尔比大于0.5时,Fe( III )EDTA的还原效率均接近100%。另一方面,碱性环境不利于 VC 转化 Fe( III )EDTA。随着温度的升高,Fe( III )EDTA 的转化率略有增加。此外,与其他还原系统相比,抗坏血酸 (VC) 被发现在还原 Fe( III )EDTA
models of the ternarycomplexes involved in the ironexchangeprocess. The main result of this kinetic study is the pertinence of the ironcomplexes of the mixed ligands as models for the transient and successive ternarycomplexes occurring in the ironexchange, which proceeds "arm-by-arm" between a homotopic ligand and the ironcomplex of another homotopic ligand.
