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-c...

Adsorption of ammonia from anaerobic digester effluent by magnetically modified zeolite (MMZ) has been investigated using a batch technique and comparison of adsorption isotherm equations. Adsorption isotherm models were utilized to describe the equilibrium isotherms and the isotherm constants were calculated. The sorption of ammonia follows Langmuir, Freundlich and Dubinin-Radushkevich (D-R) m...

We have studied the interaction of indomethacin and diclofenac solutions, on multi-walled carbon nanotube. After investigated comparative study and assigned to either indomethacin or diclofenac adsorption isotherms. The adsorption equilibrium isotherms were fitted by Freundlich, Langmuir, and Temkin models. It was found that the Freundlich model described the adsorption process better than othe...
