Background: Thermodynamic parameters are important in determining the feasibility and spontaneity of an adsorption process. They are also vital in estimating adsorptive mechanisms (i.e., physiosorption, ion exchange or chemisorption). Accurate calculation of these thermodynamic p...
This study was carried out to examine the adsorption isotherm (Langmuir, Freundlich, Temkin, and Dubinin Radushkevich adsorption isotherm) of Pb(II) and Cu(II) in order to determine the maximum adsorption capacity of chicken feather, CF. Equilibrium sorption of Pb(II) and Cu(II)...
