摘 要：The goal of the present study was to investigate the photocatalytic efficiency of titanium dioxide （TiO 2） formed on titanium （Ti） bead substrate （referred herein as TiO 2 /Ti beads） by heat treatment when exposing to ultraviolet （UV） light irradiation.Escherichia coli was used as the model test organism.The results show 4-log and 7-log decrease in bacterial concentration after a test time of 15 and 120 min,respectively,using TiO 2 /Ti beads irradiated with UV light in a tin-foil covered beaker.This article presents the potential of TiO 2 on Ti bead substrate formed by simple heat-treatment together with UV light for bacterial inactivation.
