Photocatalytic inactivation rate of phage MS2 in titanium dioxide suspensions containing various ionic species
In the TiO2 photoreaction system, the coexistence of NO3-, SO42-, PO43-, K+ or Ca2+ each at 10-100 mM decreased the rate constant for phage MS2 inactivation, but Cl-, Br- or Na+ did not. The inhibitory effects of the ions could be elucidated by the proportional relation found between the rate constants and quantities of the phage on TiO2 irrespective of the kinds of existing ions.
