类Fenton试剂处理苯酚废水的影响因素及动力学研究OA北大核心CSCDCSTPCD
Study on the influencing factors and kinetics of phenol wastewater treatment by a Fenton-like oxidation
采用一种类Fenton试剂法,即Fe3+和H2O2的组合代替Fe2+和H2O2的组合法,对氧化降解苯酚的影响因素及反应动力学进行研究.结果表明:当Fe3+、H2O2的加入量分别为1.3× 10-3和1.3×10-2mol·L-1,且初始pH值约为4时,苯酚的降解率最大,几乎达到100％.同时分别用一级动力学、二级动力学及复合一级动力学方程对该条件下的反应进行拟合,复合一级动力学方程能最佳拟合相应的动力学过程,但2个平行反应的速率系数k1≈9.24…查看全部>>
With a Fenton-like reagent(Fe3+/H2O2 )instead of Fenton reactions( Fe2+/H202 ) ,the influencing factors and kinetics of phenol wastewater treatment were experimentally studied. Results showed that the largest removal rate of phenol, which was nearly 100% ,could be reached when Fe3+dosage was 1.3×lO‐3 mol·L‐1 ,H2O2 dosage was 1. 3×lO‐2 mol·'L‐1 and initial pH ≈4. At the same time, a first-order kinetic model, a second-order kinetic model and a combined …查看全部>>
