TL;DR: In this article, an analytical methodology for the investigation of toluene photocatalytic removal at indoor-relevant concentration level (ppbv) was presented, where experiments were performed using an annular flow-through reactor with TiO 2 as photocatalyst and under different ranges of relative humidity (RH: 0-70%), inlet concentration (20-400 ppbv), and flow rate (70-350 mL min −1 ).

TL;DR: In this paper, a combined chemical precipitation and moving bed biofilm system was used to treat municipal wastewater for nitrogen removal through simultaneous nitrification and denitrification (SND), and 89.9% of total nitrogen removal efficiency through SND had been achieved in the system.

TL;DR: It has finally appeared that these biosensors are quite sensitive to Cd2+ and Zn2+ (limits of detection (LOD) = 10 ppb for a 30 min long exposure) while Pb2+ gives no significant inhibition as this ion seems to adsorb on albumin preferably.

TL;DR: In this paper, the degradation of naphthalene in water was performed by photocatalysis in UV-irradiated TiO2 suspensions, and the influence of physicochemical parameters such as concentration, photonic flux, temperature, pH and mass of catalyst has been investigated.

TL;DR: In this article, the photocatalytic activity of tetra(4-carboxyphenyl)porphyrin with different metal centers (Fe(III), Cu(II), Zn(II) and metal-free), adsorbed on TiO 2 surface has been investigated by carrying out the photodegradation of atrazine in aqueous solution and under visible light irradiation.
