DETAILED DESCRIPTION - A water silicide removal system based on capacitive adsorption comprises a water processing tank, a capacitor adsorption component arranged in the water treatment tank, a water inlet pipe connected to the water treatment tank, a pump arranged on the water inlet pipe, a stirring device arranged at the bottom of the water treatment tank, and a water outlet pipe connected to the water treatment tank. The capacitor adsorption component comprises a carrier board (B1) and a carrier board (B2) that are oppositely distributed in parallel, an anode sheet attached to the surface of the carrier board (B1), a cathode sheet attached to the surface of the carrier board (B2), a silica gel gasket that separates the anode sheet from the cathode sheet, and a direct current power supply electroconnected with the cathode sheet and the anode sheet to form a capacitor structure. The anode sheet comprises a layered structure containing a mixture (M1). The mixture (M1) comprises an anode material, PTFE and graphene oxide. The anode material is a composite. The composite comprises a mixture of three metal oxides of cerium oxide, calcium oxide and aluminum oxide and graphene oxide. The preparation of anode sheet involves obtaining the anode material, mixing the anode material, PTFE, and graphene oxide in a mass ratio of 60-75:10:10-15, adding ethanol to obtain a mixed solution after grinding, applying the mixed solution evenly on the carbon felt, and controlling the quality of the mixed solution to 0.1-0.2 g, leaving to air dry, putting in an oven at 60-100degrees Celsius and drying for 20-40 minutes. The preparation method anode material involves dispersing 35-40 mL graphene oxide in 150-250 mL deionized water, ultrasonically processing for 20-40 minutes, weighing the two inorganic metal salts of calcium and aluminum according to the molar ratio of 2:1-4:1, dissolving in the deionized water, adding alkali-source urea after ultrasonically processing for 20-40 minutes to obtain the mixed solution, feeding the mixed solution into the reactor, placing in an oven at 100-150degrees Celsius, reacting for 20-30 hours to obtain product, washing the product to neutrality, drying at 60-90degrees Celsius and grinding to small particles, calcining at 300-500degrees Celsius for 4-6 hours under argon atmosphere and heating rate of 2-5degrees Celsius/minute, and doping the cerium element according to the atomic ratio of cerium and aluminum of 1:100-10:100.
