The thermodynamic entropy S, often simply called the entropy in the context of thermodynamics, can provide a measure of the amount of energy in a physical system that cannot be used to do work. Thermodynamic parameters for the adsorption were calculated from the variations of the thermodynamic equilibrium constant (K d) by plotting of ln K d vs. 1/T. Process Experiments. Adsorption equilibrium experiments were carried out by varying the initial concentrations of dyes as 1, 10, 15, 25, 50, 100, 250, 500, 700 and 1,000 mg/L.
