Özet
Application of cetyltrimethylammoniurn bromide (CTAB) modified multi-component biosorbent composed of pine, oak, hornbeam and fir sawdust biomasses was investigated to remove Malachite green (MG) as a model pollutant from aqueous solution. The effects of pH, dye concentration, biosorbent amount and contact time on the biosorption performance were explored in a batch biosorption system. The biosorption isotherm data were analyzed using Freundlich, Langmuir, Sips and Dubinin-Radushkevich models while the kinetic data of biosorption were modeled with the pseudo-first-order, pseudo-second-order, Elovich, logistic and intra-particle diffusion models. These studies showed that Sips isotherm and logistic model fitted well to the dye biosorption data. The maximum biosorption capacity of biosorbent was calculated to be 52.610 mg g(-1) at the optimized conditions. Thus, the CTAB modified multi-component sawdust biomass can be employed as cost effective and ecological friendly biosorbent in the treatment of industrial effluents containing such unsafe pollutants.
