▎ 摘　　要

NOVELTY - Polyvinyl chloride/Graphene oxide and gold- silver nanoparticles (PVC/GO-Au@Ag NPs) complex membrane for water treatment comprises a base support layer (1) and an intermediate porous support layer (2). The base support layer is a special non-woven membrane for water treatment. The intermediate porous supporting layer is a PVC material, and a layer of GO-Au-Ag NPs coating (3) is coated on the surface of the intermediate porous supporting layer. USE - The PVC/GO-Au@Ag NPs complex membrane is useful for water treatment. ADVANTAGE - The PVC/GOAu@Ag NPs complex membrane: improves the separation effect of water treatment; prevents the agglomeration of precious metal nanoparticles; enhances the bacteriostatic effect of the antifouling membrane; and improves the hydrophilicity, chemical stability, ion selectivity and water flux. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the PVC/GO-Au@Ag NPs complex membrane. DESCRIPTION OF DRAWING(S) - The drawing shows a structural representation of the water treatment membrane.
