Özet
Simultaneous bioremoval of Basic red 46 (Br46) and Basic violet 3 (Bv3) from binary mixture aqueous system onto novel green composite biosorbent made from a combination of Spirogyra sp. and Rhizoclonium sp. green filamentous algal biomasses was investigated in this study. The impacts of various influential parameters such as pH, biosorbent amount, dye concentration and contact time were evaluated using a batch biosorption method. Biosorption equilibrium experiments indicated that the best fit was achieved with Sips isotherm model. The maximum values of biosorption from binary component system were estimated to be 53303 and 37.734 mg g(-1) for Br46 and Bv3, respectively. Kinetic modeling studies showed that the co-biosorption process of dyes from dual solution was acceptably described by the pseudo-second-order model. All these findings proposed that the algal composite biosorbent could be used for simultaneously bioremediating an effluent polluted with such dyes. (C) 2016 Elsevier B.V. All rights reserved.
