摘要：

The photodegradation has been studied of the cationic surfactant N-dodecylpyridinum chloride (N-DPCI) in aqueous heterogeneous dispersions of semiconducting catalyst particles (TiO2, Ti02/Pt and ZnO). The photooxidation was followed by UV spectrophotometry and surface tension measurements. The photodegradation approximates first order kinetics and is discussed on the basis of a simple phenomenological model. The degradation rate is almost identical for TiO2 and ZnO and higher than that for TiO2/Pt. A high mineralization yield is obtained from measurements of CO2 evolution, while an increase in the surface tension is observed. Pyridinum ring breakage, which is known to proceed with difficulty, is also indicated by the presence of NH4+ and N03-ions.
