Figure 4. Effect of pore type on water permeation and salt rejection.

Figure 4

(a) Axial velocity of water molecules in the radial direction at the location of S and Mo atom layers in the Mo only nanopore of A=56.42 Å2 at 250 MPa. (b) Axial velocity of water molecules in the radial direction at the location of S and Mo atom layers in the S only nanopore of A=57.38 Å2 at 250 MPa. (c) Cartoon representation of the pore architecture for Mo only, S only and graphene nanopore. (d) Performance of various membranes in terms of their ion rejection and water permeation rate. Water permeation rate is expressed per unit area of the membrane and per unit pressure as l cm−2 per day per MPa.
