Advanced oxidation treatment of antibiotic containing water

In advanced oxidation experiments, Amoxicillin was selected as the pollutant, and was used in form of Amoxicillin trihydrate. Studying degradation and mineralization of Amoxicillin in aqueous solution by using advanced oxidation methods, namely the Fenton and photo-Fenton treatments were the major objectives of this thesis. Various concentrations of Amoxicillin containing synthetic wastewater were prepared and used in experimental studies.Antibiotic (Amoxicillin) and TOC measurements were carried out to determine the most effective catalyst, oxidant and antibiotic concentration combinations and reaction time for advanced oxidation of Amoxicillin by Fenton and photo-Fenton and to compare the tested methods and conditions to select the most suitable method and conditions. Box-Behnken statistical experiment design method was used to determine the effects of reagent concentrations on degradation and mineralization of amoxicillin.Advanced oxidation experiments were carried out with synthetic medium containing Amoxicillin. The most suitable dosages yielding the highest Amoxicillin degradation and mineralization were determined using the Fenton and photo-Fenton treatments. In oxidation experiments; hydrogen peroxide (35 percent) was used as oxidant. The catalyst was ferrous sulphate. Sulfuric acid was used for pH adjustment. Advanced oxidation methods were compared in terms of removal performances. In advanced oxidation of antibiotic containing synthetic wastewater by Fenton?s reagent, maximum antibiotic and TOC removal efficiencies were 100 percent and 37.08 percent, respectively. In photo-Fenton oxidation, maximum antibiotic and TOC removal efficiencies were 100 percent and 50.25 percent, respectively.Both methods were proven to be effective for Amoxicillin removal. However photo-Fenton oxidation was more effective for TOC removal or mineralization.
