ABSTRACT:

The purpose of this research work, review Adsorption isotherms of complexes of some amino acids Glycine, Glutamine, Glutamic, Tryptophan and Tyrosine with chromium ion by Single–walled carbon Nanotubes (SWCNT) is a discontinuous method. By using on spectrophotometer (UV / VIS) adsorption of each complex were obtained and the relevant graph has been drawn. Review the results of experiments with models of Langmuir, Freundlich, Temkin and Dubinin-Radushkevich performed and various parameters of these models is obtained. Experimental results obtained in the temperature 295 K showed that experimental data well by these models provided and model acceptable was Freundlich model.
