Equilibrium and Thermodynamic Study of Cadmium Adsorption on Dalbergia Sissoo Sawdust
Abstract
In the present paper, the equilibrium and thermodynamic parameters of cadmium adsorption from aqueous solution on sodium hydroxide modified Dalbergia sissoo sawdust were evaluated on the basis of Langmuir, Temkin and Dubinin-Radushkevich isotherms. The adsorption of cadmium on sawdust was monolayer type, renewable and occurred by complexation mechanism. The analysis of thermodynamic data indicated that adsorption of cadmium on Dalbergia sissoo sawdust is spontaneous, exothermic and entropy driven. The linear form of Dubinin-Radushkevich isotherm was established which can be used for evaluation of saturated equilibrium concentration of adsorbate where all adsorption sites become fully occupied. The correlation between Langmuir and Temkin adsorption parameters was also explored which indicated that the magnitude of enthalpy of adsorption is equal to the heat of adsorption at half coverage. The results and interpretations based on present study may be used as a source for understanding the nature of adsorption phenomena.
