Abstract

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 other two isotherm models. The amount of NSAIDs (indomethacin and diclofenac) adsorbed on carbon nanotube surface increased with the increase of the initial NSAIDs concentration. The results show that diclofenac has most amount adsorption rate of MWCNT.
