摘要:

The electroosmotic dewatering (EOD) reported by Yoshidaet al.(3) under low-frequency A.C. conditions is shown to be equivalent to EOD carried out under D.C. conditions with periodic polarity reversal. The interpretation of their results is carried out here in terms of electrochemical considerations (e.g., pH gradients, zeta potentials) with lesser role assigned to factors considered paramount by Yoshida, e.g., heating effect in the dry region near the anode.
