dc.description.abstractSilver and cobalt doped perylene diimide supramolecular catalysts were prepared and their photocatalytic activities were tested for the removal of amoxicillin from aqueous solutions. Both bulk perylene diimide (PDI) and self-assembled perylene diimide (SA-PDI) were synthesized and silver or cobalt was doped at different weight ratios (1 % and 10 %). Among eight type of supramolecular catalysts, Ag1/SA-PDI was determined to be the most suitable photocatalyst. The effects of photocatalytic oxidation parameters including pH, catalyst loading, and the initial amoxicillin concentration were investigated by using response surface methodology. The photocatalytic reaction conditions were optimized at pH 4.6, 0.52 g/L catalyst loading, and 10.3 mg/L amoxicillin concen-tration. Under the optimum photocatalytic conditions 51.8 % amoxicillin removal efficiency was achieved. According to the radical trapping experiments, hydroxyl radicals were effective in antibiotic removal. Toxicity tests showed that L.sativum root growth inhibition was 1.1 % in treated antibiotic solutions. A kinetic study was realized to derive initial reaction rate expression. Antibiotic degradation in the presence of Ag1/SA-PDI fit second-order kinetic model. Arrhenius constant (frequency) and activation energy were calculated as 1.21 x 10(5) L.mg(-1).min(-1) and 49.7 kJ/mol, respectively.en_US
