Degradation of Alizarin Red Solution using Nanometer TiO_2 Film under UV Light Irradiation

摘要

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 TiO_2 particles, where the titanium sol synthesized by a sol-gel method was used as the binder for the immobilization. Optimal conditions of TiO_2 film, alizarin red concentration, solution pH, and UV irradiation intensity have been found to enhance the photodegradation efficiency.
