Comparative study of adsorption isotherms of vitamin C on multi wall and single wall carbon nanotube

Abstract

We have studied the interaction of Vitamin C solution on multi-wall and single-wall carbon nanotube After investigated comparative study and assigned to Vitamin C adsorption isotherm. The adsorption equilibrium isotherms were fitted by Freundlich, Langmuir, and Temkin models. It was found that the Langmuirmodel described the adsorption process better than other two isotherm models. The amount of Antioxidant drug(Vitamin C) adsorbed on Multi wallcarbon nanotube surface increased with the increase of the initial Antioxidant concentration. Based on the results, under similar conditions the efficiency of adsorption of Vitamin C by Multi-wall carbon nanotube(MWCNTs) was more thansingle-wall carbon nanotube.
