Molecular Simulations of Osmosis and Reverse Osmosis in Aqueous Electrolyte Solutions

摘要

Osmosis and reverse osmosis are phenomena of considerable importance in both life and physical sciences. Reverse osmosis is an energy-efficient technology useful for separating a wide range of solutions, including those encountered in water purification (desalination), waste treatment, and food processing (Eisenberg and Middlebrooks, 1985; Lacey, 1972; Sourirajan, 1970). In this note we report molecular computer simulation studies, using a method developed by us recently (Murad et al, 1996,1993) to study osmosis and reverse osmosis in aqueous electrolyte solution using a semi-permeable membrane.
