The Adsorption Equilibrium Isotherms Freundlich, Langmuir, and Temkin Models for Two Steroidal anti-Inflammatory Drugs (NSAIDs) Betamethasone and Clobetasol on Multi-Walled Carbon Nanotube

Abstract

We have studied the interaction of Betamethasone and Clobetasol solutions on multi carbon nanotube. After investigated comparative study and assigned to either Betamethasone or Clobetasolon adsorption isotherms. 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 SAIDs (Betamethasone, Clobetasol) adsorbed on carbon nanotube surface increased with the increase of the initial SAIDs concentration. The results show that Clobetasolon has most amount adsorption rate of Multi walled carbon nanotubes (MWCNTs).
