Permeability and separation performance of GO-based membranes. a DI water permeance of GO, rGO–TH, and rGO–TA membrane at a transmembrane pressure of 1.0 bar. b–d Permeance and rejection of organic dyes (50 µM) of GO (b), rGO–TA (c), and rGO–TH (d) membranes at a transmembrane pressure of 1.0 bar. GO membrane, 100 nm thick; rGO–TA membrane, 150 nm thick; rGO–TH membrane, 60 nm thick. e Permeance comparison of rGO–TH and rGO–TA membranes with the GO-based membranes reported in the literature14,15,16,17,18,19,20. Here, the permeance of rGO–TH and rGO–TA membranes is the maximum values that are obtained in the dye separation experiments
