概要	The photocatalyzed degrdn. of surface-active and surface-inactive naphthalenesulfonate derivs. was studied in UV-irradiated air-equilibrated heterogeneous TiO2 dispersions. The dynamics for the photodegrdn. of Na butylnaphthhalene-1-sulfonate (B-1-NS) and Na naphthalene-1-sulfonate (1-NS) are compared to those of Na dodecyl-benzenesulfonate (DBS) and Na benzenesulfonate (BS). The adsorption behavior of the surfactants on the TiO2 catalyst, cleavage of the arom. ring, mineralization to CO2, formation of sulfate ions, and the temporal changes of the surface activity (surface tension) against UV irradn. time were probed exptl. to provide inferences on the photoinitiated mechanism.
