| 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 pHIEP(isoelectric potential) of the porous membrane is equal to 9.20; In the range of 2.00
