| 摘 要： | 探讨不同pH值、H2O2和Fe2 浓度下Fenton试剂氧化降解甲醛的规律,比较均相催化过程和非均相过程Fenton试剂氧化降解甲醛的效果。发现在其它条件相同的情况下,pH值在3.2时,Fenton试剂的氧化性能最强,适当的H2O2和Fe2 浓度有利于甲醛的降解,以活性炭为载体吸附Fe2 制成的非均相催化剂具有更强的催化性能。

| Abstract: | The effects of the concentration of pH value,catalyst concentration and oxidant concentration on the dynamics of formaldehyde oxidized by Fenton reagent were studied.The performances of heterogeneous and homogeneous Fenton reaction were compared.The results showed that Fenton reagent has the highest oxidizability while pH value is 3.2.Moderate H_2O_2 and Fe~(2 ) concentration will advantage the degradation of formaldehyde.The heterogeneous catalyst-activated carbon with Fe~(2 ) adsorbed on,has a higher oxidizability than that of homogeneous catalyst. |
