As shown in Fig. 4, the adsorption capacity increased rapidly
with the initial increase in concentration and then slowed as it
approached a maximum. In the design of sorption systems, the
equilibrium sorption isotherms are very important from fundamental
point of view. The equation parameters and the underlying
thermodynamic assumptions of these equilibrium models often
provide some insight into both the sorption mechanism and the
surface properties and affinity of the sorbent (Ho, Porter, & McKay,
2002). In order to investigate the sorption isotherm, Langmuir
model and Freundlich equilibrium model were applied.
The experimental isotherm data were fitted to Langmuir model
and Freundlich isotherm for nonlinear regression analysis. The fit
plots were presented in Fig. 5 and the correlation parameters for
each model were listed in Table 1. The coefficient b in Langmuir
