Abstract: PURPOSE: A polyamide nano separation membrane obtained by adding a polyvinyl alcohol layer as a protecting layer to a polyamide active layer having low chemical stability such as chlorine resistance is provided, which has excellent chemical stability in wide ranges of pH as well as high water permeability. CONSTITUTION: The nano separation membrane is characterized in that it comprises a cross linked polyvinyl alcohol as a protecting layer on a polyamide composite comprising a porous supporting body and a polyamide active layer, wherein the cross linked polyvinyl alcohol has a thickness of 0.01 to 0.1 micrometer. The membrane is prepared by adding a mixture solution of one or two or more ionomers selected from the group consisting of sodium alginate, chitosan and sulfonated polystyrene with polyvinyl alcohols to a polyamide active layer.
