In this research we have studied aimed to compare the adsorption of dexamethasone by two adsorbent; multi-wall carbon nanotube and activated carbon with the help of UV/VIS spectrophotometer Jenway 6505 model. Adsorption chart based on the wavelength of dexamethasone has been obtained and the relevant graph is plotted by considering factor of concentration. Four different concentrations necessary for adsorption of dexamethasone on multi wall carbon nanotube and activated carbon the maximum adsorption rate was determined. Study with on the results, the efficiency of that observation adsorption dexamethasone by multi wall carbon nanotube was more than activated carbon. The results can be useful in biological system and pharmacy.

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).

We have studied the interaction of Acetaminophen and Diclofenac solutions, on multi ncarbon nanotube. After investigated comparative study and assigned to either Acetaminophen or Diclofenac adsorption isotherms. The adsorption equilibrium isotherms were fitted by Freundlich, Langmuir, and Temkin models. It was found that the Temkin model described the adsorption process better than other two isotherm models. The amount of NSAIDs (Acetaminophen 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.
