Degradation of Alizarin Red Solution Using Nanometer TiO₂ Film under UV Light Irradiation

Abstract

This paper explores the sol-gel titanium dioxide the conditions of experiments to determine the best conditions. The photodegradation capability of alizarin red has been enhanced by using immobilized TiO2 particles, where the titanium sol synthesized by a sol-gel method was used as the binder for the immobilization. Optimal conditions of TiO2 film, alizarin red concentration, solution pH, and UV irradiation intensity have been found to enhance the photodegradation efficiency.
