▎ 摘　　要

NOVELTY - The method involves energizing solution. A Cr is deposited on a surface of silver particles (1) on a conductive porous network graphene electrode to cause passivation. The conductive porous network graphene electrode (4) is turned in a container 180?o. An ultrasonic vibration or high-frequency electric field is applied to make the passivated silver particles fall off. New unpassivated silver particles are reattached to the graphene electrode. The steps of energizing and applying ultrasonic vibration or high-frequency electric field are repeated until all silver particles complete the passivation. The solution is dried to obtain the passivated silver particles. A pH value of the solution containing the passivation solution is 2-9. A solvent is water, methanol or ethanol. A solute is H2O2, diaminotriazole, acrylic resin, epoxy resin, tannic acid, phytic acid and organic molybdate and chromium. A mixture of chromium, sulfate ion, chlorine, Nitrate ions and alkali metal ions. USE - Surface passivation treatment method for silver particles. ADVANTAGE - The method processes the silver particles with different particle sizes.
