Abstract

Background & Objectives: Antibiotics can cause negative impacts on animals and bacterial resistance by entering to the environment. CATALYTIC OZONATION process is a method for increasing the efficiency of the simple ozonation. This study evaluated the efficiency of CATALYTIC OZONATION process with activated carbon modified with MGO to remove METRONIDAZOLE from aqueous solutions in a FLUIDIZED BED REACTOR.Materials & Methods: CATALYTIC OZONATION experiments were performed in a FLUIDIZED BED REACTOR. Impact of pH, reaction time, catalyst dosage, initial concentration, radical scavengers and hydroxyl radicals was found. The degradation kinetic of METRONIDAZOLE was determined as well as FTIR spectra of the catalysts. The concentration change of METRONIDAZOLE was determined by HPLC.Results: The results showed that the catalyst prepared increases METRONIDAZOLE decomposition rate as high as 7.32 times, compared to conventional ozonation. The optimum pH of 10, the optimal dose of 1.5 g/L of catalyst and the optimum time of 30 min were determined. The results of radical scavengers’ effect showed the main reactions of METRONIDAZOLE decomposition are on the catalyst surface.Conclusions: The results showed that, due to the high performance activated carbon coated with MGO in CATALYTIC OZONATION process, increased removal of METRONIDAZOLE, compared with simple ozonation, and easy access to raw materials, the use of these catalysts in ozonation process are recommended to increase efficiency and accelerate the METRONIDAZOLE decomposition reaction and similar compounds.
