Removal of Reactive Black 5 azo dye from aqueous solutions by catalytic oxidation using CuO/Al2O3 and NiO/Al2O3

CuO Nanoplate Array Supported on Ni foam, a Highly Active Catalyst in the Degradation of Rohdamine B with Hydrogen Peroxide

“…22% activity decrease after 2 cycles [13]), CuO/activated carbon (ca. 21.5% activity decrease of after 4 cycles [14]), CuO/Al 2 O 3 (25.6 % activity decrease after 3 cycles [9]). …”

“…Thus, it is of great importance to fabricate nanostructured CuO catalysts in the form of film. Generally speaking, catalysts in the form film have much higher stability and reusability than that of powdery counterpart [9,10]. In addition, if the nanostructured films are well designed, they can also have high catalytic activity in degradation of organic pollutants with hydrogen peroxides.…”

Removal of heavy metals from their aqueous solutions through adsorption onto natural polymers

“…Different technologies and processes are currently used to remove such pollutants from the wastewater. Biological treatments (Gonç alves, da Costa, Leite, & Sant'Anna, 2007;Taş tan, Ertugrul, & Dönmez, 2010;Viggi et al, 2010), membrane processes (Bessbousse, Rhlalou, Verchère, & Lebrun, 2008;Mbareck, Nguyen, Alaoui, & Barillier, 2009;Zou et al, 2009), advanced oxidation processes (Bradu et al, 2010;ElAshtoukhy & Amin, 2010;El-Desoky, Ghoneim, El-Sheikh, & Zidan, 2010;Osugi et al, 2009), chemical and electrochemical techniques (Belkacem, Khodir, & Abdelkrim, 2008;Raghu & Basha, 2007), and adsorption procedures are the most widely used techniques for removing metal and dyes from industrial effluents.…”

Molecular docking study investigating the possible mode of binding of C.I. Acid Red 73 with DNA

“…The discharge of this wastewater into water bodies not only damages aquatic plants and animals but also causes serious environmental problems [2][3][4]. Different classes of dyes are used in industrial applications, and azo dyes are used most frequently, thus constituting 60-70% of all dyes employed [5][6][7].…”
