摘要
以5-磺基水杨酸(SSA)和亚铁离子通过配位反应制备5-磺基水杨酸亚铁配合物(Fe(Ⅱ)-SSA),用其催化H_2O_2产生·OH降解水中苯酚。实验表明:在室温(20℃)和初始pH值为7的条件下,催化剂摩尔比为1:1,浓度为0.8m M,过氧化氢浓度19.6m M,Fe(Ⅱ)-SSA催化苯酚(50mg/L)的降解率达到88.04%,显著优于硫酸亚铁体系(74.09%)。苯酚降解反应动力学为一级反应。可应用于处理中性条件下苯酚废水。
With Sulfosalicylic acid and Ferrous sulfate as raw material,Ferrous Sulfosalicylic acid(Fe(Ⅱ)-SSA)was prepared by complexing method to catalytze H_2O_2 into OH to degrade phenol in water. The results indicated that in initial pH of 7 at room temperature(20 ℃)the catalyst molar ratio was 1:1, 0.8 mM Fe(Ⅱ)-SSA,19.6mM hydrogen peroxide, 88.04 % of phenol was degraded for a solution containing 50 mg/L of phenol,obviously superior to Ferrous sulfate(74.09 %). Phenol degradation reaction was first order reaction. Fe(Ⅱ)-SSA was suitable for treatment of phenol wastewater under neutral condition.
