Tóm tắt

The clogging of sieving pores due to the complex sewage system of mixed molecules and nanoparticles of different scales is a difficulty in the membrane-based separation process. When the holes are reduced to the point where they can repel small molecules in the contaminants, large-molecule contaminants can adsorb to the holes and decrease the permeability. A similar question remains in new promising graphene oxide (GO) membranes. In this study, we prepared a small lateral-sized reduced graphene oxide (S-rGO) membrane with short Z-type water transport pathways and a lower adsorption energy for pollutant molecules. The S-rGO membrane presented an ultrahigh permeability for large size microplastics (MPs) of 236.2 L m
