Phenol was investigated for the ability of TiO2 photocatalysis to increase its bioavailability as an electron donor for denitrification. The rate of nitrate removal by denitrification was increased by up to 2.6-fold by exposing phenol to photocatalysis for 30 min, although the rate decreased with increasing photocatalysis. The increased denitrification rate appeared to be associated with the photocatalytic production of carboxylic acids, but the slow down correlated to the production of catechol and hydroquinone.
