Graphene oxide offers a promising opportunity to fabricate highly efficient and pressure-endurable membranes in terms of water permeability while demonstrating high level solute rejection. However, achieving higher permeance with an excellent separation capability is still challenging. Herein, we report class graphene oxide-lignin biopolymer (GOLB) for the first time prepared by functionalizing GO nanosheets lignin extracted from plant pulp. Lignin most abundant, green, low-cost, environmentally friendly material variety oxygen functional groups. The as-prepared GOLB have unique laminated structure that provides rejection (>99%) several organic dyes, proteins, biomolecules variable molecular weight exhibits ultrawater ∼1300 L m–2 h–1 bar–1, more than reported GO-based membranes. It interesting due larger interlayer spacing, such show less (<10%) salts, i.e., NaCl, MgCl2, Na2SO4, etc. Furthermore, these are stable up 37 days aqueous environment 28 acidic basic solutions compared pristine

Abstract Environmental water contamination, particularly by heavy metal ions, has emerged as a worldwide concern due to their non-biodegradable nature and propensity accumulate in soil living organisms, posing significant risk human health. Therefore, the effective removal of ions from wastewater is utmost importance for both public health environmental sustainability. In this study, we propose design membrane consisting fluorographene (F-GRA) nanochannels investigate its ion capacity through molecular dynamics simulation. Although many previous studies have revealed good performance lamellar graphene membranes desalination, how zero-charged functionalized fluorine atoms (fully covered negative charges) affects still unknown. Our F-GRA exhibits an exceptional permeability accompanied ideal rejection rate. The superior removing can be attributed charge surface, which results electrostatic attraction positively charged that facilitates optimal capture. analysis potential mean force further reveals molecule lowest free energy barrier relative when passing channel, indicating transport energetically more favorable than ion. Additional simulations show higher permeabilities compared with membranes, while robustly compromising meal rates, thus better performances. Overall, our theoretical research offers approach future industrial treatment.
