ABSTRACT
The possibility of application of the process of photocatalytic decomposition of humic substances (humic acid – HA) to their removal from water was investigated. Commercial TiO2 (Evonic-Degussa P-25) and the periodic reactor were used in the experiments. The decomposition under artificial sunlight (ASL) and UV irradiation was tested. It was stated that ASL irradiation is not sufficient to cause significant decomposition of HA whereas TiO2 appeared to be very effective under the UV irradiation. Strong adsorption of HA on the surface of TiO2 was observed.
