铁碳微电解降解磺胺甲恶唑和卡马西平
|
摘要
以两种典型人工合成有机物(磺胺甲恶唑和卡马西平)为主要研究对象,采用铁碳微电解法降解上述两种目标污染物,研究了铁碳质量比、反应时间、pH、铁投加量等因素对磺胺甲恶唑和卡马西平降解效果的影响.结果表明,pH=1,铁碳比为1∶1,铁投加量为80 g·L~(-1)时,磺胺甲恶唑的去除率最高,60 min几乎全部去除.pH=1,铁碳比为1∶4,铁投加量为80 g·L~(-1)时,卡马西平的去除率最高,60 min卡马西平去除率接近90%.在这过程中磺胺甲恶唑和卡马西平发生氧化还原反应,它们的氮被还原成氨氮.磺胺甲恶唑和卡马西平的降解符合假一级反应动力学.
Iron-carbon microelectrolysis was employed to degrade two synthetic compounds sulfamethoxazole and carbamazepine. The effects of iron carbon mass ratio, reaction time, pH, iron dosing quantity and other factors on the degradation rate of sulfamethoxazole and carbamazepine were investigated. The results showed that sulfamethoxazole was completely removed within 60 minutes when pH=1,Fe∶C=1∶1,Fe=80 g·L~(-1). The highest degradation efficiency of carbamazepine(90%) occurred at 60 minutes with pH=1, Fe∶C=1∶4,Fe=80 g·L~(-1). Sulfamethoxazole and carbamazepine undergone redox reactions and the nitrogen was reduced to ammonia nitrogen. The degradation of sulfamethoxazole and carbamazepine was in accordance with pseudo first order reaction kinetics.
