Özet
In this study, a renewable biosorbent material was prepared from biological waste of widespread coastal plant,Zostera marinaand employed for the biosorption of heavy metal pollution from water environment in green way. Manganese was selected as a model heavy metal to evaluate the treatment efficiency of prepared biosorbent. The batch biosorption behavior of biosorbent was investigated by the characterization, parameters evaluation, kinetic and equilibrium studies. The characterization study showed that the biosorbent has a rough surface and various binding groups for the heavy metal ions. The heavy metal concentration of 30 mg L-1, time of 60 min, pH of 6 and biosorbent amount of 10 mg were determined as the optimum biosorption conditions. The pseudo-second-order equation was found to be the best among kinetic models applied. The equilibrium data were best explained by Freundlich isotherm. The maximum biosorption efficiency based on Langmuir model was predicted as 58.426 mg g(-1). Hence, the current work presents a renewable alternative biosorbent substance for the green treatment of heavy metal pollution from water medium.
