Effect of agitation, turbidity, aluminium foil reflectors and container volume on the inactivation efficiency of batch-process solar disinfectors.
TL;DR: It was shown that agitation promoted the release of dissolved oxygen from water with subsequent decrease in the inactivation rates of E. coli, and total inactivation was achievable in 300 NTU samples within 8 h exposure to strong sunshine.

The ''Direct-Indirect'' model: An alternative kinetic approach in heterogeneous photocatalysis based on the degree of interaction of dissolved pollutant species with the semiconductor surface
TL;DR: In this article, the direct-indirect (D-I) model was proposed to predict the functional dependence of photooxidation rate on the experimental parameters (photon flux and pollutant concentration), distinguishing between strong and weak semiconductor-reactant interaction.
