摘要: 采用电渗方法研究了经硫酸溶液氧化并利用逆向电解方法剥离后的铝阳极氧化多孔膜层的ζ电位与溶液pH的关系.结果表明:该多孔膜层在1.0×10-2mol/LKCl溶液中的pH等电点(pHIEP)=9.20,2.00<pH<9.20,ζ>0,多孔膜荷正电;9.20<pH<11.00,ζ<0,多孔膜荷负电.

关键词: 铝阳极氧化多孔膜层, ζ电位, 等电点

Abstract: Using electrodialytic method, the relation between the pH value of tested solution and the ζ potential of porous anodized aluminum membrane, which was separated by reverse electrolysis from aluminum substrate, has been investigated. The following results can be obtained in 1.0×10-2 mol/L KCl solution: The pHIEP(isoelectric potential) of the porous membrane is equal to 9.20; In the range of 2.00
