dc.description.abstractA novel alkaline-treated multi-component biosorbent composed of pine, oak, hornbeam and fir sawdust biomasses was evaluated to eliminate a common hazardous dye [malachite green (MG)] from aqueous solution in this study. Batch biosorption studies were carried out using this base-modified biosorbent under varying biosorption conditions of: pH, MG concentration, modified biosorbent loading and reaction time. The experimental results showed that this easy modification application (using 0.3-M sodium hydroxide) was able to enhance the biosorption potential of natural biosorbent from 35.230 to 78.926 mg g(-1) under the same study conditions. The obtained equilibrium data were modelled using Freundlich, Langmuir, Sips and Dubinin-Radushkevich isotherm models. Also, the biosorption kinetics were analyzed using the pseudo-first-order, pseudo-second-order, logistic and intra-particle diffusion models. It was found that the biosorption data of the isotherm and kinetics were best represented using Sips and logistic models. Hereby, this modified biosorbent can be used for bioremediation of contaminated areas with such deleterious dyes.
