Abstract
Here, we have studied the purification of water from phenol and tetracycline by oxidation with ozone and hydroxyl radicals generated in a corona electric discharge. Liquid circulation has been used to process large volumes. It has been established that tetracycline decomposes from a concentration of 11 mg/L to (1.7 ± 0.3) × 10−3 mg/L at a dose of 140 J/50 mL. Phenol decomposes more slowly, the oxidation rate decreases at low residual concentrations. The phenol concentration decreases from 13 mg/L to (27 ± 5) × 10−3 mg/L at a dose of 5 × 104 J/50 mL. The reasons for the strong decrease in the rate of phenol oxidation at low concentrations in the case of oxidation by hydroxyl radicals are analyzed.
