摘要：

Aqueous suspensions of Escherichia coli and TiO2 (anatase) were irradiated with a ELF lamp (320nm<lambda<420nm). The inactivation rate for an initial E. coli level of 10(3) cells/mL was 1.78x10(-2)/min for light intensity of 67.9 mu E/s.m(2) in the presence of lmg/mL TiO2. Optimum TiO2 loading and the effect of light intensity are also reported. (C) 1997 IAWQ. Published by Elsevier Science Ltd.
