Photochemical disinfection of Escherichia coli with a TiO2 colloid solution and a self-assembled TiO2 thin film

Abstract

Effect of long-wavelength irradiated TiO₂ colloid solutions on E. coli disinfection and the kinetics mechanism have been investigated. In addition, uniform thin films of TiO₂ are deposited on an ordinary glass by self-assembled techniques. The modified glass also shows the photokilling effect on bacteria in the air.
