Preparation of Blend Film of Sodium Alginate and Polyvinyl Alcohol and Its Adsorption for Ions
The blend film of sodium alginate and polyvinyl alcohol was prepared and the blend film was investigated in relation to its adsorption behavior for low concentration ions including As(Ⅴ),C(rⅥ)and Cu2+.Results indicated that the blend film had good properties,with high water resistance and high percentage of removing ions.
