摘要：以水/载O3有机溶剂（全氟萘烷）为新型两相臭氧氧化体系，研究了臭氧在全氟萘烷中的溶解度和稳定性，并考察了pH、NaHCO3和叔丁醇对两相体系中臭氧稳定性的影响；以水体中氯霉素为研究对象，考察了初始pH值、臭氧投加量和自由基抑制剂对两相臭氧氧化体系降解氯霉素效果的影响。结果表明：初始水相pH增大有利于氯霉素的降解；碳酸氢钠对两相体系氧化降解氯霉素影响不显著。

Abstract:Study was carried out for the removal of Chloramphenicol from aqueous solution by using the two-phase ozonation system of water/perfluorodecalin organic solvent loaded ozone. Perfluorodecalin has a high ozone stability and solubility. Chloramphenicol was used to examine the efficiency of the two-phase ozonation system. During the experiments, effects of pH and free radical scavenger on the removal rate of Chloramphenicol were investigated respectively. The results showed that the efficiency of two-phase ozonation was increased with the increase of initial pH in water. It was also observed that bicarbonate had no significant negative effect in two-phase ozonation.
Key words: ozonation; perfluorodecalin; two-phase ozonation; degradation; chloramphenicol
