The adsorption isotherms of the car

The adsorption isotherms of the carbon materials were investigated.
The classic equations of Langmuir (Eq. (3)) and Freundlich
(Eq. (4)) were used to fit the experimental equilibrium adsorption
data. Allthe parameters are listed in Table 2, while the fitting curves
are shown in Fig. 5. It was observed that the Langmuir equation
offers the best fit to the adsorption isotherms for most samples,since the values of R2 obtained are higher than for the Freundlich
model
