Present research paper deals with the adsorption isotherms rate 2-amino phenol and 4-amino phenol on multi-wall carbon nanotube which performed by changing the amount of solution concentration in ppm unit. According to difference between two under studied substances are in substitution of NH₂ in ortho and para position , more adsorption of 4-aminophenol on carbon nanotube demonstrate that para position has more adsorption in relation to ortho position .calculation of adsorption isotherms performed by Langmuir, Freundlich and Temkin and relative parameters of each model presented . Taken result in constant temperature laboratory distributes more acceptable identity between data and models, and appears best identity in Freunlich model.
