Over 10,000 different dyes are commercially available with a total annual production of approximately 7 x 105 MT (Pathania et al., 2013). It is estimated that 15% or approximately 1.05 x 105 of these dyes are lost in industrial effluents during the manufacturing and processing operations (Auta & Hameed, 2011; Aksu, Tanaci, & Tunc; Agarwal, Gupta, Pathania, & Singh, 2012).
