It was possible to fabricate the Al anodic oxide separation membrane having pore diameter of 7nm by anodic oxidation method which used 5% sulfosalicylic acid -0.2% sulfuric acid mixing aqueous solution for electrolytic solution. Decrease of pore diameter and formation of a coating film on the porous layer were confirmed, when the sol-gel coating was conducted to this separation membrane. The acid resistance of coated anodic oxidation separation membrane improved 1.5〜1.8 times in comparison with it before the coating. Next, the permeabilities of chromate (VI) ion from aqueous solution by the electrodialysis using the membrane was examined. As the result, permeabilities of the chromate (VI) ion increased from 0% after sol-gel coating to 88【encircledA】'90% before coating, when commercial Al anodic oxide membrane having pore diameter of 20nm was used for supporting membrane. On the other hand, permeabilities of the chromate ion increased from 88〜90'/. To 99〜99.5% by the sol-gel coating, when Al anodic oxide separation membrane having pore diameter of 7nm was used. Furthermore the separation of organic dyestuff and chromate (VI) ion by the electrodiaiysis in mixing aqueous solution of organic dyestuff and organic dyestuff was carried out by the equipment using membranes of two sheets, in which pore diameter differs.

以5%磺基水杨酸-0.2%硫酸混合水溶液为电解液，采用阳极氧化法制备孔径为7 nm的铝阳极氧化分离膜是可能的。当对该分离膜进行溶胶-凝胶涂覆时，确认了孔径减小和在多孔层上形成涂膜。涂层后的阳极氧化分离膜的耐酸性比涂层前提高了1.5 ~ 1.8倍。接着，通过使用该膜的电渗析检查铬酸根（VI）离子从水溶液的渗透性。结果表明，当使用孔径为20 nm的商用铝阳极氧化膜作为支撑膜时，铬酸根（VI）离子的渗透率从溶胶-凝胶涂覆后的0%增加到涂覆前的88 ± 90%。另一方面，铬酸根离子的渗透率从88 × 90 ~（-1）/cm ~ 2增加。当使用孔径为7 nm的铝阳极氧化分离膜时，通过溶胶-凝胶涂层，可达到99 ± 99.5%。此外，还用两种不同孔径膜的装置，在有机染料和有机染料混合水溶液中，进行了有机染料和铬酸根离子的电渗析分离。
