| Research Abstract |
Fluorine-bearing pharmaceuticals are acted as an endocrine disruptor to cause serious contamination in ecological aquatic environment. The advanced oxidation processes in the addition of ozone and/or hydrogen peroxide led the detoxication for recalcitrant chemicals. In order to sever the strong C-F bond, the photoassisted defluorination by gallium oxide catalysis was carried out to generate fluorine ions. The Pt-loading Ga2O3 catalyst enhanced the defluorination yield. The opimal conditions of defluorination were investigated. Therefore, non-degradable substances were easily mineralized and their degraded intermediates had no mutagenicity by the Ames test.
