SEM images of the surface morphology of the bead cellulose shows that it has spherical shape and abundant porous structure on its surface. The mapping images of aluminum and silicon of the composite (PSCAS) present aluminum(Ⅲ) oxide and silicone are uniformly dispersed on the surface. The adsorption behavior of PSCAS toward metal ions was determined.展开更多
