In this study, the adsorption of three different blue anthraquinone dye classes (Reactive, Acid and Disperse dyes) were investigated using activated carbon fibre prepared from polyacrylonitrile (PAN) waste. The use of polyacrylonitrile based activated carbon fiber (PAN-ACF) for the adsorption of these dyes has been examined using exhaustion method at different operational conditions such as dye co...
