where Q m(mg/g)is the maximum adsorptive capacity;K L(L/mg)and K F( (mg/g)(L/mg) 1/n) represent the Langmuir and Freundlich constants,respectively;and n is the heterogeneity factor.Figure 7 b,c show the data fi tted with the Langmuir and Freundlich isotherm models,respectively,and Table 1 lists the related model parameters and correlation coeffi cients.The correlation coeffi cient(R 2)for the Langmuir model(0.9986)is much higher than that for the Freundlich model(0.9102),which means that the Langmuir model is more eff ective in describing the adsorption process.This result indicates that the adsorption sites are basically homogenous.
