The equilibrium analysis of the copper ions biosorption process using hazelnut shells as a biosorbent is presented in this paper. The experimental data were analyzed using the non-linear forms of three empirical isotherm models, namely the Langmuir isotherm model, the Freundlich isotherm model and the Temkin isotherm model. The performed analysis indicated that the Temkin isotherm model was the best fit for the analyzed data (R2=0.9847). The equilibrium analysis also showed a negligible difference between the experimentally obtained (qe,exp) and model calculated (qe,m) biosorption capacities, which indicates that the hazelnut shells are almost completely saturated with copper ions.
