Heterogeneous Do–Do model of water adsorption on carbons

Water adsorption with hysteresis effect onto microporous activated carbon fabrics

“…Furmaniak et al proposed a "Heterogeneous Do-Do Model" that accounts for different energies of adsorption at different functional sites (Furmaniak et al 2005). However, without prior knowledge of the nature of functional sites on the material, one must make guesses as to the number and properties of the sites the material may have.…”

Parameterization of the corrected Dubinin–Serpinsky adsorption isotherm equation

“…3). We showed previously that this effect can be achieved if one takes into account the differences in the energy of water adsorption on surface-active centers [14,15]. In the case of data measured on carbon D the Langmuirian part of the isotherm is strongly pronounced; thus the value of the parameter A 4 is high.…”

“…3 present the results obtained from such a simultaneous fitting. The adsorption isotherm and related enthalpy relationships were fitted to experimental data by applying the minimization procedure using the differential evolution (DE) algorithm proposed by Storn and Price [12,13], and described in detail recently [15]. It should be pointed out that the difference between values of the two sets of fitted parameters is insignificant.…”

Simple models of adsorption in nanotubes

“…3 shows the results of the fitting of both proposed models (NT-BET, solid lines, and NT-PFG, dashed ones) to their data for selected pore diameters (H = 2, 5, and 8 nm). We fitted the data applying the genetic algorithm constructed by Storn and Price [24,25] and previously applied by us with great success [26,27]. The results for the NT-PFG model are shown in Table 1 and it is seen that we obtained determination coefficient (DC) values in the range 0.940-0.997.…”
