مستخلص: The photodegradation of organic pollutants by TiO2 has previously been shown to be efficient, but the TiO2 particles are typically so fine that they are easily washed away. This problem was solved by forming a complex between TiO2 and bentonite. Four different photodegradation conditions (i.e., no catalyst, addition of 3 bentonite, addition of 1 TiO2, and addition of 3 TiO2-bentonite) were investigated for their degradation efficiencies of 20 mg/l sodium dodecyl benzene sulfonate (SDBS) under ultraviolet light for 6 h. The titanium content of 1 titanium oxide was equal to that of the 3 Ti-bentonite. The results showed that, under the four above conditions, 36.7%, 25.9%, 96.7%, and 99.3%, respectively, of SDBS were degraded in the aqueous solutions. The latter two conditions degraded SDBS more efficiently than the former two conditions. The TiO2-bentonite complex possessed more advantages than TiO2 or bentonite alone, making the bentonite an appropriate carrier for TiO2.
