摘要：

A comparative study is made of 12 methods of chemical oxidation applied to degrading p-hydroxybenzoic acid in aqueous solution. The oxidation processes tested were: UV, O-3, UV/TiO2, O-3/Fe2+, O-3/H2O2, O-3/UV, UV/H2O2, H2O2/Fe2+, H2O2/Fe2+/O-3, UV/H2O2/O-3, H2O2/Fe2+/UV and Os/UV/H2O2/Fe2+. The 12 processes were ranked by reactivity. In a kinetic study, the overall kinetic rate constant was split up into three components: direct oxidation by UV irradiation (photolysis), direct oxidation by ozone (ozonation), and oxidation by free radicals (mainly OH.).
