| Research Abstract |
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.
