The adsorption parameters resulting from both isotherm models applied in this work to a selection of toxic metal ions on SiNL are listed in Table 2. Clearly, the best fits were obtained with the Langmuir model (Figure 9

As seen from Table 2, when the Langmuir model was used to fit the experimental data in Figure 7a, the calculated value the maximum MB adsorption capacity was approximately 1634.36 mg/g, and the determination coefficient R2 = 0.9879. The value of R2 (0.7669) obtained from the Freundlich

For the adsorption isotherms of Cu2+ on Lys-GO in Figure 7b, the calculated value of the maximum Cu2+ adsorption capacity was approximately 156.91 mg/g, and R2 was equal to 0.6722 using the Langmuir model. As compared with the Langmuir model, the

In spite of its simplicity, the model is able to describe a rich phenomenology which goes beyond the standard Langmuir model usually considered for FEBID, enabling the study of multilayer systems. Moreover, it can describe processes involving both chemi- and
