项目摘要

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,采用阳极氧化法可制得孔径为7 nm的铝阳极氧化物分离膜。对该分离膜进行溶胶-凝胶法涂膜,证实了膜孔径的减小和多孔层上涂层的形成。涂层阳极氧化分离膜的耐酸性比涂层前提高了1.5~1.8倍。其次,考察了使用该膜的电渗析对水溶液中铬(VI)离子的渗透性能。结果表明,用孔径为20 nm的商用铝阳极氧化膜作为支撑膜,铬(VI)离子的渗透率从溶胶-凝胶涂层后的0%提高到涂层前的88[环绕A]‘90%,而铬酸根离子的渗透率则从88~90’/增加。当采用孔径为7 nm的氧化铝阳极分离膜时,溶胶-凝胶法可使膜的成膜率达到99~99.5%。在有机染料和有机染料混合水溶液中,利用两片不同孔径的膜实现了有机染料和铬(VI)离子的电渗析分离。
