Graphene oxide nanofiltration membranes for desalination

WebGraphene membranes (GMs) are usually formed through simple stacking of graphene, graphene oxide (GO), and reduced graphene oxide (rGO) (Zhu et al. 2024). The layered structure of GO offers unique ion transport properties, and its excellent water dispersibility makes it easy to prepare in the form of membranes (Tsou et al. 2015). Synthetic grade graphite powder (lateral size <20 micron), hydrochloric acid (HCl), concentrated sulfuric acid (98% H2SO4), sodium hydroxide pallets (NaOH), potassium persulfate (K2S2O8), phosphorus pentoxide (P2O5), potassium permanganate (KMnO4), glucose (C6H12O6), xylose (C5H10O5), … See more In a typical membrane fabrication run, GO dispersions (1.00 mg ml−1, labelled ‘reagent A’) were prepared following our previous work using a modified Hummers method10. 1 ml GO dispersion was dispersed into 450 ml … See more Since the vacuum filtration is carried out in a ‘dead-end’ mode, the degree of TBO incorporation in the membrane is easily determined from the difference in TBO concentration … See more SEM (Hitachi SU 8010 FESEM, operated at 5 keV, 10 µA) was used to obtain the GO coating thickness for the 9-cm-diameter membrane coupons and examine the coating uniformity for the large-area GO–TBO … See more Reduced GO (rGO) dispersions (1.00 mg ml−1, labelled ‘reagent C’) were prepared following our previous work10.
