“…From this point of view, we have been interested in enhancing the decolorization efficiency of the Alpill-MMT by doping with copper (II) in the present study because the copper (II) could not only act as catalyst in advanced oxidation processes (AOPs) (Lahtinen et al, 2005;Yang et al, 2007;Punniyamurthy and Rout, 2008;Wang et al, 2009;Wang et al, 2013), but also antibacterial agent (Majzlik et al, 2011;Yu-Hao et al, 2011). The AOPs are one of the most attractive and effective methods for wastewater treatment because the AOPs have the ability to generate the highly reactive hydroxyl radicals (HO ), in which they can attack a wide variety of organic contaminants in wastewater, resulting in decolorization, degradation and mineralization to CO 2 and H 2 O (Al-Kdas et al, 2004;Bach et al, 2009;Grrido-Ramirez et al, 2010). In addition, the copper (II) was selected as dopant in this work because it was claimed to have greater catalytic activity for AOPs than iron catalysts in some researches (Tomul, 2011;Zhou et al, 2011).…”
