Abstract: Based on analyzing the principle of continuous demulsification of liquid emulsion membrane by a centrifugal pulse electric field, a set of centrifugal pulse electric field continuous demulsifier was designed and fabricated with vertical cylinder insulated electrodes, which was used in laboratory. The effects of various factors on continuous demulsification were studied in extracting Cu²⁺ experiment by the liquid emulsion membrane composed of M6401-L113B-kerosene-H₂SO₄ or Lix984N-L113A-kerosene-H₂SO₄ from waste water. It is shown that the continuous demulsification by the centrifugal pulse electric field was successful. And the continuous demulsifying effectiveness of a centrifugal pulse electric field is better than that of a pulse electric field.
