钼酸铁在邻苯二甲酸氧化降解中的催化性能研究

Study of Catalytic Properties of Iron Molybdate Catalyst to Phthalic Acid Oxidative Degradation

研究了钼酸铁作为类Fenton试剂对邻苯二甲酸的催化氧化性能。考察了催化剂用量、H2O2浓度和反应温度对邻苯二甲酸去除率的影响。结果表明,当催化剂用量为1000 mg/L,H2O2浓度为4.995 mg/L,反应温度40℃时,反应90 min后,邻苯二甲酸的去除率可达92.36%。

The catalytic properties of iron molybdate, which is used as a Fenton-like reagent was studied by phthalic acid. The influencing factors, such as catalyst dose, H2O2 concentration and reaction temperature were investigated on the removal of phthalic acid. Results showed that removal efficiency of phthalic acid can reach 92.36 % at 90 min reaction time under following conditions： catalyst dose 1000 mg/L, H2O2 concentration 4.995 mg/L, reaction temperature 40 ℃.
