The First Step in Studying the Ability of Destroying the Antibiotics by Gamma Radiation

This paper presents the research results of the possibility to destroy the antibiotics in the form of liquid by gamma radiation to break the molecular bond of antibiotics. The 60Co gamma radiation with the doses of 4.7 kGy to 29.3 kGy was irradiated on chloramphehicol and flumequine solution to define the content of antibiotics by the high performance liquid chromotography method. After irradiating, concentration of antibiotics is reduced from 30.26% to 98.89%. Based on the results, we can draw the conclusion that, with appropriate doses, the gamma radiation can destroy antibiotics. This result can be used to destroy after-content of antibiotics in seafood products. (author)
