Polar and steric effects in reverse osmosis

Abstract The effects of polar parameter Σσ * and steric parameter Σ E s on reverse osmosis separations of alcohols, aldehydes, ketones, and ethers (noncyclic) in aqueous solutions involving single solute systems and porous cellulose acetate membranes are discussed. The least‐squares and multiple‐regression analyses of solute transport parameter data show that the separation of aldehydes, just as that of alcohols, is predominantly a function …
