This research has studied equilibrium adsorption isotherms of Ketotifen on carbon nano-tube. And also results of experiments through Freundlich,Temkin and Langmuir models have been studied and it has found different parameters of these models for carbon nano-tube adsorbent. According to the error rate for each model, we obtained a good agreement between these data which it showed the best agreement by Langmuir model. With the spectrophotometer (UvVis); it obtained the adsorptionn diagram based on wavelength for Ketotifen Experimental result showed that by increasing concentrations of Ketotifen, therefore adsorption rate will increase too. The highest adsorption rate is for 5 ppm concentration of Ketotifen.
