Kinetic study for photocatalytic degradation of Direct Red 23 in UV–LED/nano-TiO2/S2O82− process: Dependence of degradation kinetic on operational parameters

Monitoring of TiO2-catalytic UV-LED photo-oxidation of cyanide contained in mine wastewater and leachate

“…There have been a lot of works on the photo-catalytic oxidation using UV-LED and TiO 2 (Chen et al, 2005;Vilhunen et al, 2010;Natarajan et al, 2011;Rojviroon et al, 2012;Wang et al, 2012;Jo and Tayade, 2014;Rasoulifard et al, 2014;Umar et al, 2015), but all of them dealt with photo-catalytic degradation of organic compounds. A few researches focused on the photo-oxidation of inorganic contaminants rather than organic compounds, especially on cyanide (Frank and Bard, 1977;Augugliaro et al, 1997Augugliaro et al, , 1999Ibrahim et al, 2003;Dabrowski et al, 2005;Marugán et al, 2009;Karunakaran et al, 2011;Ozcan et al, 2012;Bagabas et al, 2013).…”

As-synthesized ZSM-5 zeolite as a suitable support for increasing the photoactivity of semiconductors in a typical photodegradation process

“…where [C] o and [C] t represent the concentration of the substrate in solution at zero time and t time of irradiation, respectively, and k represents the apparent rate constant (min À 1 ) [24]. In order to study the kinetics of the reaction, ln(C o /C) was plotted versus irradiation time.…”

Hierarchical flower-like titanium phosphate derived from H-titanate nanotubes for photocatalysis

“…It is 89.2 % for TiP-F-300, and it is increased to 100 % for TiP-F-600 after 60 min. The kinetic data on the photocatalytic degradation of MO are analyzed to investigate the effect of calcination temperature on the photocatalytic activity [42,43], as shown in Fig. 8c.…”
