TL;DR: In this article, aqueous TiO2 dispersions under UV illumination was examined to assess the influence of temperature, pH, concentration of dissolved oxygen (DOC), initial concentration of MB, and light intensity on the kinetics of decomposition.

TL;DR: In this paper, the authors explored the choice of optimal experimental parameters for the photodegradation of DBS with a concentrated solar illumination device and found that the foam produced at the higher TiO 2 loadings exhibited greater stability than in the absence of TiO2.

TL;DR: In this paper, a commercial detergent whose major components are an anionic surfactant and a fluorescent whitening agent can be photodegraded in aqueous TiO 2 dispersions under irradiation with concentrated sunlight in the presence of air.

TL;DR: The photoassisted TiO(2)/O(3) hybrid method may prove to be an efficient combination to enhance wastewater treatment of recalcitrant drug pollutants in aquatic environments and show a strong pH dependence of the adsorption of FXT on TiO (2) and the crucial role of adsor adaptation in the whole degradation process.

TL;DR: In this paper, solar photo assisted remediation of a simulated wastewater contaminated with 2-chlorophenol (2-CP) was carried out by various advanced oxidation processes in a pilot-plant-scale Pyrex glass tubular-type photoreactor using solar cell derived electricity to drive the whole setup.
