- Abstract
The use of antibiotics in lactating dairy cows produces waste milk containing antibiotic residues. Antibiotics have been one of the emerging pollutants in the environment. Waste milk is a concentrated wastewater because it contains organic matter at high concentrations. The objective was to clarify the removal characteristics of chlortetracycline and cefazolin contained in waste milk using the electrochemical oxidation by a comparative study with in aqueous solution. This paper discussed partial and preferential oxidation of the antibiotic dissolved in milk to reduce the energy consumption during the treatment. The preferential degradation of antibiotic as a target compound on the basis of pseudo-first-order reaction kinetics led the charge saving treatment. The results indicated that the electrochemical oxidation can effectively treat the low levels of the antibiotic residues even in concentrated wastewater not only in usual dilute solutions.
