概要	The TiO2-photoassisted degrdns. of the anionic dodecylbenzenesulfonate (DBS) and cationic hexadecyltrimethylammonium (HTAB) surfactants were examd. in aq. media along with the cationic/anionic 1:1 binary complexes of DBS/HTAB. The processes were monitored by surface tension measurements, total org. C assays and CO2 evolution. The degrdn. of the anionic surfactant was significantly involved in prior adsorption of the species on the pos. charged metal-oxide particle surface. By contrast, the degrdn. of the cationic surfactant was rather limited owing to the lack of adsorption on the TiO2 surface under the same conditions. An adsorption model is proposed for the binary complexes on the metal-oxide surface.
