Abstract
Photodegradation process and mechanism is a relative new and eco-friendly process to recycle and reuse of water. Some investigation concerned with effort to increase photocatalyst activity by immobilizing semiconductor oxide such as ZnO in clay as solid support. It was related to that photodegradation was directed by adsorption mechanism. However sometimes the activity of a photocatalyst is not linearly correlated with adsorption mechanism. In this research evaluation on photoactivity of ZnO-hectorite (ZnO/CTMA/Hectorite) and TiO2-montmorillonite based material using statistical approximation compared to the linear model is studied. The model is evaluated for photodegradation of phenol solution. Some beneficial results of the probit model are (i) the guarantee of activity prediction value in the range of 0-100% (ii) interaction of adsorption and photodegradation mechanism is well described.
