The results shows the capacity of the anode oxidation membrane decreases with the increasing of oxidation potential, and there exists relationship between impedance and behavior anode polarization.
The membrane potential of shaly sand was influenced by the cation exchange capacity, hydrocarbon saturation and concentration difference of the contacted solutions.
