The removal of copper (II) ion by using mushroom biomass (Agaricus bisporus) and kinetic modelling
Özet
The efficiency of Agericus bisporus as an adsorbent for removing Cu(2+) ions from synthetic wastewater has been studied. Batch adsorption experiments were carried out as a function of contact time, pH, zeta potential of particles, initial metal ion concentration and temperatures. Cu(2+) uptake was very rapid during the first 5 min. Contact time was observed in 30 min. The extent of metal ion removed increased with increasing initial metal ion concentration. Maximum metal sorption was found to occur at initial pH 5.0. Adsorption equilibrium data was calculated for Langmuir, Freundlich, Dubinin-Radushkevich and Temkin isotherms at different temperatures. It was found that biosorption of Cu(2+) was better suited to the Freundlich adsorption model than other adsorption models. To study the kinetics of adsorption, batch adsorption models were applied, using pseudo-first and second-order mechanisms at different initial concentrations of Cu(2+). The best result came from the second-order mechanism.
