ABSTRACT:

In this article, adsorption of some amino acids and their complexation with lanthanum(III) ion on carbon nanotube (MWCNT) by using of three relations Langmuir, Freundlich and Temkin isotherms was investigated. From this relations, Freudlich and Temkin relations predict good equilibrium diagram in isotherm condition. We could compute the theoretical constants by excel software. By considering these constants, it is clear that among amino acids used and also amino acids were formed complex,l-arginine in comparison with other showed the most adsorption on carbon nanotube.
