Cellulose Acetate Membranes: Electron Microscopy of Structure

R Riley et al. Science. .

Abstract

Electron photomicrographs of cellulose acetate membranes used in the reverse osmosis processof water desalination reveal a dense surface layer with a porous substructure. The high rate oftransmission for water can be correlated with the thickness of the dense layer on the air-driedsurface of the membrane.
