The thermodynamic parameters of Gibb's free energy (G), enthalpy (H), and entropy (S) changes related with the uptake of various cationic dyes onto the adsorbents were computed using Gibb's free energy and the Where Kc is the distribution coefficient of adsorption, T is the absolute temperature (K). R is the universal as constant. (8.314 J/mol.K), Ce is equilibrium concentration in solution (mg/L) and Ca is the solid phase quantity at equilibrium (mg/L).
