Figure 9From: Atrazine adsorption removal with nylon6/polypyrrole core-shell nanofibers mat: possible mechanism and characteristicsLangmuir (A) and Freundlich (B) isotherms model for adsorption. Plot to estimate thermodynamic parameters for adsorption (C). Two well-known models of Langmuir and Freundlich isotherms were used to fit the equilibrium data. The plot of lnK d versus 1/T gives a straight line with a slope of ΔH° and an intercept of ΔS°.Back to article page
