SolarFenton是一种重要且广泛使用的高级氧化工艺(AOP),用于降解药物污染物。本研究的目的是评估混合污染物(阿莫西林,对乙酰氨基酚,和环丙沙星)用于使用太阳能Fenton工艺的水溶液。操作参数,如pH,铁剂量,H2O2剂量,污染物浓度,研究了时间。从实验结果来看,获得了去除混合污染物的理想条件,如pH3,Fe2+0.04mM,H2O24mM,混合污染物的浓度为5mg/L,太阳辐射400W/m2,时间10分钟,分别。利用伪一级动力学研究了混合污染物的降解效率。研究结果表明,混合污染物的降解效率>99%。观察到最大63%的矿化,和羟基自由基清除剂的效果进行了研究。最佳条件用于评估加标废水(市政废水(MWW)和医院废水(HWW))。AMX的最高消除率,ACET,和CIP为65%,89%,MWW占85%,76%,92%,HWW占80%,分别。通过LC-ESI-MS在水基质(水溶液和加标废水)中检测降解的副产物,并对转化产物进行了ECOSAR分析。研究得出的结论是,太阳能Fenton技术对于去除水基质中的混合污染物是有前途且有效的。
Solar Fenton is an important and extensively used advanced oxidation process (AOP) to degrade pharmaceutical pollutants. The objective of this study was to evaluate the performance of simultaneous degradation of the mixed pollutants (amoxicillin, acetaminophen, and ciprofloxacin) for an aqueous solution using the solar Fenton process. Operating parameters such as pH, iron doses, H2O2 doses, pollutant concentrations, and time were studied. From the experimental results, the ideal conditions were obtained for the removal of mixed pollutants such as pH 3, Fe2+ 0.04 mM, H2O2 4 mM, the concentration of the mixed pollutants 5 mg/L, solar radiation 400 W/m2, and time 10 min, respectively. The pseudo-first-order kinetics were utilized to investigate the degradation efficacy of the mixed pollutants. The result of the study indicates that the degradation efficiency was > 99% for the mixed pollutants. A maximum of 63% mineralization was observed, and hydroxyl radical scavenger effects were studied. The best optimal conditions were applied to assess the spiked wastewater (municipal wastewater (MWW) and hospital wastewater (HWW)). The highest elimination rates for AMX, ACET, and CIP were observed as 65%, 89%, and 85% for MWW and 76%, 92%, and 80% for HWW, respectively. The degraded by-products were detected by LC-ESI-MS in the water matrix (aqueous solution and spiked wastewater), and ECOSAR analysis was performed for the transformed products. The study concluded that the solar Fenton technique is promising and effective for the removal of mixed pollutants from the water matrix.
