Evaluation of Adsorption Isotherms of Freundlich, Temkin and Langmuir of Loratadine Drug on Multi-walled Carbon Nanotube

Abstract

This research has studied equilibrium adsorption isotherms of Loratadine as a drug 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 nanotube absorbent. 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 adsorption diagram based on wavelength for Loratadine. Experimental result showed that by increasing concentrations of Loratadine therefore adsorption rate will increase too. The highest adsorption rate is for 5 ppm concentration of Loratadine.
