中文摘要：
采用电-Fenton法处理青霉素钠（Penicillin Gsodium,PGN）模拟废水,当T=20℃,pH=3时,投加0.5g·l^-1 FeSO4和0.2ml·l^-1 H2O2,在0.6A电流下降解青霉素钠废水（100mg·l^-1）,20min后青霉素钠去除率为79%,40min后去除率为95%.拟合实验数据得到青霉素钠降解反应的速率方程式为：-d[PGN]/dt=2.35×10^6 exp（-32869.4/RT）[Fe^2＋]^0.53[H2O2]^0.8[PGN]^1.14反应速率常数和反应级数表明,初始阶段降解反应进行非常迅速,且H2O2浓度比Fe^2＋浓度对电-Fenton降解反应的影响重要.
英文摘要：
The degradation of penicillin G sodium （PGN） simulate wastewater by electro-Fenton has been investigated. Operating at T = 20℃, pH = 3, Fe^2＋ concentration = 0. 5g·l^-1 , H2O2 concentration = 0. 2ml·l^-1, PGN concentration = 100mg·l^-1 and electric current =0. 6A, about 79% of PGN was removed at 20rain, and 95% of PGN was removed at 40min. The overall equation for PGN degradation by electro-Fenton process is： - d [ PGN ]/dt = 2. 35×10^6 exp [ - 32869. 4/RT] [ Fe^2＋]^0. 53 [ H2O2 ]^0.8 [ PGN ]^1. 14 The reaction rate constant and reaction order indicate that the reaction rate is very fast and the effect of initial H2O2 concentration is greater than initial Fe^2＋ concentration on PGN degradation bv electro-Fenton.
