This research we etched the surface of titanium plate by electrochemical methods and prepare Pd modified electrode by using electro-deposition to improve the load capacity of the matrix Ti. This process improved the ability of matrix Ti loading Pd and reduce the shedding Pd from Ti electrodes and extended the electrode ’ s life. The apparent morphology and surface morphology were characterized by Scanning electron microscopy (SEM) method, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). That electrode was applied to electrochemical degradation of 2, 4-DCP through studying current intensity ’ s effect on its degradation efficiency. In the degradation, 2, 4-DCP removal rate increased gradually with current intensity which went on to 5mA, the removal rate was 90.1%, then when it went on at 10mA and 20mA, the rate almost unchanged which is between 91.9% and 90.9%. The degradation of 2, 4-DCP followed false kinetics levels
