Thermodynamic Study on the Adsorption of Cd+2 Ions from Aqueous Solution by Seagrasses (original) (raw)
This work was to study batch biosorption of Cd (II) ions from aqueous solution by Powdered Seagrasses (PSG). The optimum conditions for the adsorption of Cd (II) ions from aqueous solution by seagrasses were investigated by considering the extent of adsorption with respect to contact time, initial metal ion concentration and temperature. The results obtained indicates that the extent of metal ions removed decreases with increasing contact adsorption equilibrium data best fitted Freundlich adsorption isotherm. Thermodynamic study indicated that the adsorption of Cd (II) ions onto seagrasses was spontaneous and endothermic in nature.
