  • 摘要:利用FeFerron逐时络合比色法对类Fenton与Fenton体系中Fe(Ⅲ)水解形态的转化规律进行了比较.结果表明,水解度越高,两体系中Fe(Ⅲ)的水解速度也越快,但水解度相同时,与Fenton体系相比,类Fenton反应生成的Fe(Ⅲ)的水解速率要低,且Feb所占比例也较少.与Fenton体系一致,类Fenton体系中的Fe(Ⅲ)水解速率随H2O2浓度的增加而减缓.
  • Abstract:Fe(Ⅲ) hydrolyzing characteristics in Fenton and Fenton-like processes was investigated using Ferron assay. It was found that the Fe(Ⅲ) hydrolyzing rates increased with the increase of formation function in both the Fenton system and Fenton-like system. Under the same formation function, however, both the Fe(Ⅲ) hydrolyzing rate and the ratio of Feb in Fenton-like system were markedly lower than that in Fenton system. Similar with that in Fenton system, the Fe(Ⅲ) hydrolyzing rate in Fenton-like system decreased with the increase of H2O2 concentration.
