  <dc:description xml:lang="eng">Abstract:
In this paper Langmuir, Freundlich, and Temkin adsorption isotherm models were used for describing the adsorption of copper ions onto
walnut shells. The adsorption was performed in a batch system. The obtained isotherm data were fitted using the mentioned models, and
the isotherm parameters were calculated from the linearized plots corresponding to each model. The Langmuir adsorption isotherm
model showed the best agreement with the analyzed experimental data, with the correlation coefficient R2 = 0.993. According to this
model, the adsorption process occurs until a complete monolayer of copper ions is formed on the surface of the walnut shells. The
maximum adsorption capacity, according to this model, was 7.71 mg g
-1.</dc:description>
