Abstract

This work investigated the potential of semiconductor photocatalysis for the treatment of drinking water. More specifically it determined the effect of the following operational parameters on the adsorption, rate of initial degradation, and mineralisation of Aldrich humic acid solutions: concentration, temperature, oxygen, light intensity, and pH.The kinetics of humic acid degradation were found to be complex due to the heterogeneity and high molecular weight of these compounds. Models which are often applied to semiconductor photocatalysis did not fit; the high adsorption of humic acid on the titanium dioxide surface needed to be taken into account.
