A linear correlation between ce/qe and ce in Eq.（2）at different temperatures is shown in Figure 7.The results and the corresponding regression coefficient（R2）at different temperatures are listed in Table 1.The R2 at different temperatures are all near 0.99，showing that the experimental data can be fitted to the Langmuir adsorptive isothermal equation very well.As shown in Figure 7，the slope of the line decreases slightly with an increasing temperature，which proves that qm increases slightly with the increase in temperature，indicating that the affinity between the CuIYIIIY zeolite and BT molecules is enhanced with an increasing temperature.The values of qm obtained from Figure 7 are in good agreement，with the results shown in Figure 6.The Langmuir constant KL decreases with an increasing temperature as evidenced by the data from Table 1，illustrating that the adsorption process is exothermic.
