Abstract

The objective of this work is to study the adsorption behavior of celebrex as non-steroidal anti-inflammation on single-walled carbon nanotubes (SWCNTs). As the function of temperature and initial concentration of adsorbate were observed through adsorption isotherms, the amount of celebrex adsorbed on carbon nanotube surface increased with the concentration at constant temperature, and decreased with the increase of temperature at constant concentration. The experimental results obtained at the temperatures of 295, 300 and 305 K showed that the experimental data were properly represented by the Langmuir, Freundlich and Temkin isotherm models.

Key words: Adsorption, celebrex, non-steroidal, carbon nanotubes.
