“…The conventional methods for the removal of dyes in effluents include adsorption (Can et al, 2003;Jeon et al, 2008;Yamamoto et al, 2007), flocculation (Ciardelli and Ranieri, 2001), electrochemical methods (Szpyrkowicz et al, 2001;Vlyssides et al, 2000), membrane separation (Tan et al, 2006) and ozonation (Kusvuran et al, 2004;Matheswaran and Moon, 2009;Zhang et al, 2009). In addition, dye decomposition using homogeneous or heterogeneous catalysts along with hydrogen peroxide resulted in higher treatment efficiencies (Azbar et al, 2004;Melero et al, 2009;Taralunga et al, 2005;Yang et al, 2008). Fenton's reagent (a mixture of H 2 O 2 and Fe 2þ /Fe 3þ ) is one of the most common homogeneous catalytic systems for decomposition of synthetic dyes (Meric et al, 2004;Sun et al, 2007;Ramirez et al, 2005;Karci, 2014).…”
