Özet
This study is focused on the investigation of the equilibrium, thermodynamics and kinetics of arsenic(III) biosorption from aqueous solution by dead green algae (Maugeotia genuflexa) biomass. Optimum biosorptin conditions were determined under the optimum pH, biomass concentration, contact time, and temperature. The equilibrium data were applied to the Langmuir, Freundlich and Dubinin–Radushkevich (D–R) isotherm models. From the Langmuir model, the maximum monolayer biosorption capacity of the biosorbent was found to be 57.48mg/g at pH 6, biomass concentration 4g/L, contact time 60min, and temperature 20°C. The calculated mean biosorption energy (10.2kJ/mol) using D–R model indicated that the biosorption process was carried out via chemical ion-exchange. Biosorbent could be regenerated using 0.5M HCI solution, with up to 96% recovery and permitted a slightly decrease about 20% in …
