“…As could be seen, ≈10% of the dye was mineralized. The obtained results confirm that the degradation of RO16 was only partial, but the rate of the achieved decolorization is much faster than in photocatalytic processes, 31,32 except when H 2 O 2 was added. 33…”

Electrochemical decolorization of the Reactive Orange 16 was studied using dimensionally stable Ti/PtOx anode in the chloride containing solution. Different reaction parameters, agitation speed, applied current, sodium chloride concentration, and dye concentration was varied and optimum electrolysis conditions were suggested. The hypohlorous acid was suggested to be an active species in the electrochemical decolorization. Reaction was also studied using UV-Vis spectrophotometry, high-pressure liquid chromatography (HPLC), and total organic carbon (TOC) and total nitrogen (TN) analyses.

“…The results suggest that photocatalytic process with solar light irradiation is a feasible technique for phenol removal. The use of solar light could be an excellent alternative since this natural source of energy could reduce the costs for the treatment of phenolic wastewaters [22][23][24][25].…”

A B S T R A C TThe solar photocatalytic treatment of phenolic wastewater over TiO 2 suspensions was investigated. The study focused on the effect of various operating parameters on the treatment efficiency including chlorides (50-200 mg/L), sulphates (50-200 mg/L), aeration (pre-aeration, with and without aeration), liquid volume (0.25-1.5 L) and solar light intensity (throughout the year). The presence of chloride and sulphate ions decreased the degradation rate of phenol due to a decrease in the adsorption of the pollutant and act as hydroxyl ion scavengers. It was observed that the phenol removal efficiency was 30, 85 and 77% for pre-aeration, with and without aeration, respectively. The phenol removal efficiency was 99, 94 and 79% and 46% for wastewater volume of 0.25, 0.50, 1.0 and 1.5 L, respectively. It was observed that as the volume of wastewater was increased, the phenol removal was found to decrease. The phenol removal efficiency reached its maximum of 95% at maximum UV light intensity of 32 W/m 2 and the minimum phenol removal efficiency of 59% at minimum UV light intensity of 20 W/m 2 .

2014) Photodecomposition of dimethyl phthalate in an aqueous solution with UV radiation using novel catalysts, Desalination and Water Treatment, 52:16-18, 3377-3383, A B S T R A C TThis study investigates the photolytic and photocatalytic degradation of dimethyl phthalate (DMP) with novel catalysts including the titanium dioxide-coated magnetic poly(methyl methacrylate) (TiO 2 /mPMMA) and platinum-doped TiO 2 /mPMMA microspheres. The experiments under the illumination of ultraviolet (UV) radiation at 185 and 254 nm are conducted to examine the effects of the initial DMP concentration, photocatalyst, and Pt doping on the degradation of DMP and its mineralization efficiency. The photocatalyst and initial DMP concentration are important factors for the degradation of DMP, while the Pt doping has a minor effect. On the other hand, the mineralization efficiency would be significantly accelerated by the presence of photocatalysts and the Pt doping. In addition, it demonstrates the remarkable contribution of UV radiation at 185 nm to the elimination of DMP and intermediates via both direct photolysis and photocatalysis. This study provides useful information about the direct photolytic and photocatalytic degradation of DMP using the novel photocatalysts with the presence of UV radiation at 185 nm.
