The pseudo-second-order model represented the biosorption kinetic data well. Among biosorption isotherm models, Sips model provided the best fit to the equilibrium data. The phyco-composite biosorbent exhibited best performance at pH 9 with maximum biosorption capacity of 55.953 mg g(-1) for Br46. The mean free energy (E) from Dubinin-Radushkevich isotherm equation and the standard Gibbs free energy change (Delta G degrees) revealed a feasible, spontaneous and physical biosorption process. Thus, this novel composite material can be used as a promising biosorbent to remove such unsafe colorants from aqueous media. (C) 2016 Elsevier B.V.
