Adsorption of Metformin as Anti-Diabetic Drug On Carbon Nanotube and Activated Carbon.

We have studied the adsorption of the isotherm of Metformin, on multi carbon nanotube. The adsorption equilibrium isotherms were fitted by Freundlich, Langmuir, and Temkin models. It was found that the Langmuir model described the adsorption process better than other two isotherm models. The amount of Metformin adsorbed on carbon nanotube surface more than of activtad carbon surface also adsorption on both adsorbent increased with the increase of the initial Metformin concentration.
