The thermodynamic process of two macroalgae, Sargassum fusiforme and Lamin aria japonica, absorbing heavy, metal ions Cu^2 , Pb^2 , Cd^2 and Ni^2 . has been studied. The result indicates that the absorption isotherms of these two macroalgae clearly accord with the Landmuir adsorption model. The absorptive processes of S. fusiforme and L. japonica for Cu^2 are endothermal, and at 35℃, the adsorption heat of these two algae is 59.5kJ/mol and 76.8 kJ/mol respectively. Temperature could affect the algae‘s adsorption capacity. Their adsorption capacity increases with temperature (25℃ and 35℃).  相似文献
