چکیده
Currently, sulfate-radical-based advanced oxidation processes are promising candidates to become viable post-treatment for wastewater purification. In this work, a continuous flow UV light/persulfate (PS)/zero-valent iron (ZVI) system has been applied treatment the first time. The influence of certain photo-Fenton-like process parameters, such as space time, PS concentration, and ZVI molar ratio, on removal total organic carbon (TOC), was examined using Box–Behnken design. First, synthetic municipal used experiments, polynomial regression model constructed utilizing real data by response surface methodology (RSM). adequacy RSM assessed analysis variance, which showed that reliable could be improve parameters TOC removal. Moreover, both were spiked with carbamazepine (CBZ), is commonly prescribed an antiepileptic drug, investigate its fate in UV/PS/ZVI system. With time 60 min, concentration mM, ratio 15, it possible remove 71% completely CBZ from wastewater, whereas 60% complete achieved at 50 PS/ZVI 15 wastewater. This difference possibly linked complex matrix presence radical scavenging agents.
