Abstract

Si-immobilized Sargassum horneri was used to study the adsorption characteristics along with maximum adsorption conditions of heavy metal ions, Cd(II) and Ph(II) on the Si-immobilized Sargassum horneri. More amount of Cd(II) and Pb(II) ions on the Si-immobilized Sargassum horneri than Sargassum horneri were adsorbed. And Pb(II) ions were more adsorbed in all algae than Cd(II) ions more effectively in alkaline than in acidity. Recovery ratios of Cd(II) and Pb(II) ions on the Sargassum horneri were 58.0-62.6%, 61.2-64.4% respectively, Si-immobilized Sargassum horneri 56.8-92.7%, 37.8-47.9%. Recovery ratio of Cd(II) ion was higher on the Si-immobilized Sargassum horneri but it of Pb(II) ion was lower on the Si-immobilized Sargassum horneri.
