  • 摘要: 应用Fenton高级氧化技术降解水溶液中抗生素磺胺间甲氧嘧啶钠(SMMS),系统探讨了起始pH、CSMMS、CFe2+、CH2O2和温度等因素对SMMS降解效果的影响。结果表明:CSMMS = 4.53 mg/L, pH = 4.0, CH2O2 = 0.49 mmol/L, CFe2+ = 19.51 μmol/L, T = 25℃为最佳反应条件。在最佳条件下,87.4%的SMMS可以在120 min内降解。反应动力学研究表明Fenton氧化降解SMMS分为两个阶段,快速反应阶段和慢速反应阶段,并建立了两阶段动力学模型,模型拟合结果较好。研究结果为含有SMMS的污废水处理提供了基础数据和科学参考。
    Abstract: Fenton oxidation was applied to degradate sulfamonomethoxine sodium (SMMS) in aqueous solution. The operation parameters of pH, temperature, and concentrations of H2O2, Fe2+ and SMMS were investigated. The optimum conditions for Fenton processes were determined as follows: CSMMS=4.53 mg/L, pH=4.0, CH2O2=0.49 mmol/L, CFe2+=19.51 μmol/L and T=25℃. Under these conditions 87.4% of the SMMS were degradated. The kinetics was also studied, and degradation of SMMS by the Fenton process was found to be a two-stage process, in which fast degradation followed by stagnant degradation. Based on experimental data, a two stage kinetic model was established and the model matched experimental data very well. This process could be used as a pretreatment method for wastewater containing sulfamonomethoxine sodium.
