Ultrahigh water permeance of a reduced graphene oxide nanofiltration membrane for multivalent metal ion rejection

Abstract

We develop a kind of pure rGO membrane using amino-hydrothermal reduction that exhibits an ultrahigh water permeance of 142.5 L m−2 h−1 bar−1 while still maintaining a high rejection rate of 91.6% for multivalent metal ions. The prepared rGO membranes have two types of spacing: larger hydrophilic spacing and smaller hydrophobic spacing, resulting in superior filtration performance. This provides a new avenue for multivalent metal ion separation using pure rGO membranes.
