dc.description.abstractWastes from different sources can be utilized as effective materials in wastewater bioremediation. From this point of view, this study was aimed to investigate the possibility of using pistachio shell, a non-conventional cheap biosorbent, obtained as agricultural solid waste for removal of a reactive-azo dye from water. The batch biosorption studies were carried out as a function of dye concentration and contact time. The experimental results showed that the biosorption process was very rapid (nearly 10 min) and the percent yield of biosorption decreased with an increase in dye quantity. Two- and three-parameter biosorption models were employed to describe the experimental kinetic and isotherm data. The results revealed that the biosorption data were best fitted by the pseudo-second order and Sips models. The maximum biosorption capacity was found to be 109.535 mg g(-1). The magnitude of standard Gibbs free energy change was calculated as -5.184 kJ mol(-1) showing that physical forces were involved in the spontaneous biosorption of dye onto the biosorbent. This research suggests that the pistachio by-product can be an effective and low-cost material for the removal of such hazardous dyes from water. (C) 2016 Elsevier B.V. All rights reserved.
