摘要
The thermodynamics of aniline adsorption from aqueous solution on polyvinyl alcohol Sn(IV) tungstate nano composite cation-exchanger was studied. The nano composite cation-exchanger was prepared by surfactant assisted sol-gel precipitation method and characterized to elucidate the morphology, particle size, crystallinity and structure using SEM, TEM, X-RAY and FTIR. The nano composite cation-exchanger possessed flakes like morphology with particle size in the nano range. The analytical applicability and thermodynamic parameters like Delta H, Delta G and Delta S of this nano composite were also calculated. The thermodynamic parameters showed that the adsorption of aniline onto nano composite cation-exchanger is feasible, spontaneous and exothermic.
