▎ 摘　　要

NOVELTY - The nanofilter (100) has graphene oxide layers (102) fixed between first and second porous plates. An adjusting control unit (110) sets one of the pressure and distance between the first and second porous plates based upon a desired filtration cutoff. A seal is arranged between the first and second porous plates and surrounds the graphene oxide layers. A first porous substrate filter is fixed between the graphene oxide layers and the first porous plate. A second porous substrate filter is arranged between the graphene oxide and the second porous plate. A first flow channel is arranged on upstream of the first porous plate. A second flow channel is arranged on downstream of the second porous plate. USE - Nanofilter i.e. graphene oxide nanofilter for filtering aqueous solutions and water-based fluids for facilitating dialysis and seawater purification. ADVANTAGE - The nanofilter reduces materials costs by minimizing width of expensive secondary filters without undermining compressive strength for constraining and setting stacked thickness of graphene oxide layers and tests the nanofilter across range of separation distances to empirically determine correlation between separation distance. The nanofilter prevents larger molecules from entering stage, while allowing permeation of smaller-sized molecules and medium-sized molecules. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for facilitating nanofiltration of aqueous solutions. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene oxide nanofilter.
