This study investigates the transport of water and ions through membranes formed from carbon nanotubes (CNTs) using molecular dynamics simulations under hydrostatic pressure and equilibrium conditions. The research aims to explore the potential of CNT membranes for efficient water desalination using reverse osmosis. The study finds that CNT membranes incorporating tubes with diameters ranging from 6 to 11 Å are promising for water desalination. The size and uniformity of the tubes are crucial for achieving desired salt rejection. Ions face a significant energy barrier and cannot pass through narrower tubes ((5,5) and (6,6) "armchair" type tubes), while water can pass through all tubes at very high rates due to the formation of stable hydrogen bonds. By measuring the conduction rate under hydrostatic pressure differences, the study shows that CNT membranes can achieve high desalination efficiency at flow rates far exceeding those of existing membranes. The results suggest that efficient desalination using CNT membranes is possible, with potential flow rates up to 1500 times higher than current technologies. The study also provides insights into the transport properties of water and ions in CNTs, highlighting the importance of tube size and uniformity in achieving optimal desalination performance.This study investigates the transport of water and ions through membranes formed from carbon nanotubes (CNTs) using molecular dynamics simulations under hydrostatic pressure and equilibrium conditions.
