Investigation Of The Effect Of Structure On Reactivity In The Titanium Dioxide Mediated Photodecomposition Of Phenols And Haloethers When Irradiated At 350 Nm In An Aqueous Medium, Claudia Cardona
FIU Electronic Theses and Dissertations
Three studies were performed to obtain fundamental mechanistic information on the TiO2 catalyzed photooxidations of organic substrates irradiated at 350 nm in dilute aqueous solutions under oxygenated conditions: (a) The photodecomposition of three haloethers, 2-chloroethyl ether, 4-chlorophenyl phenyl ether, and 4-bromophenyl phenyl ether, was investigated in an aqueous media at pH 7.0. (b) A comparative study of structure-reactivity was conducted on para-substituted phenols whose substituents range from electron-withdrawing to electron-donating in an aqueous media at pH 3.0. (c) The initial rates of the TiO2 catalyzed photodegratation of phenol were studied in an aqueous media at pH 1.0, …
