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.
电子显微镜照片显示,用于海水淡化反渗透过程的醋酸纤维素膜具有致密的表层和多孔的亚结构。水的高传输速率与膜风干表面致密层的厚度有关。
