Potential of Maize Cobs for Removal Zn(II) and Ni(II) in Aqueous Systems
نویسنده
چکیده
In this study, the ability of maize cobs to bind Zn(II) and Ni(II) was investigated as a function of initial metal ions concentration, at pH = 7.5. Freundlich and Langmuir adsorption models expressed the sorption phenomena of metal ions on the maize cobs. The best results were obtained for Freundlich isotherms. On the bases of this study, it may be concluded that maize cobs can be used as low-cost sorbent, natural and abundant sources for the removal of metal ions from aqueous systems.
