OF THE THESIS 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 MEDIA. by Claudia Cardona Florida International University, 1994 Miami, Florida Professor Kevin E. O'Shea, Major Professor Three studies were performed to obtain fundamental mechanistic information on the TiO 2 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, 4chlorophenyl 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 Ti2 catalyzed photodegratation of phenol were studied in an aqueous media at pH 1.0, 3.0, 5.0, 7.0, 9.0, 11.0, and 13.7 and a pH effect profile was obtained and compared to the removal efficiency after four hours of irradiation. Controls were
