The result shows that the value of n is greater than unity
(n = 1.2633) indicating that the dye is favorably adsorbed on PS. This
is in great agreement with the findings regarding to RL value. The
magnitude of Freundlich constant indicates easy uptake of MB from
aqueous solution.
The adsorption data for MB on PS were analyzed by a regression
analysis to fit the Temkin isotherm model (Fig. 6). The parameters
of Temkin model as well as the correlation coefficient are listed
