Özet
This paper was focused on the biosorption of phosphate ions from aqueous solution onto the cetyltrimethylammonium bromide (CTAB) modified multi-component biosorbent composed of pine, oak, hornbeam and fir sawdust biomasses. A series of batch tests were conducted and the effects of solution pH, ion concentration, quantity of biosorbent and contact time on the bioremoval of phosphate ions were investigated. The biosorption data of kinetic and equilibrium were modeled using various mathematical equations. The phosphate removal increased with increased ion concentration and decreased with increased pH and biosorbent quantity values. The equilibrium state was reached within 120 min of exposure time. The process kinetics was best described by Elovich model while the isotherm data of biosorption best obeyed Freundlich equation. The obtained results revealed that the use of CTAB modified mix sawdust biosorbent presented interesting options for bioremediation of contaminated environments and waste recycling (as nutrient fertilizer and compost material).
