NOVELTY - Method for preparing a polypyrrole/graphene oxide (PPy/GO) composite electrode, involves (i) adding pyrrole monomer to sodium dodecylbenzenesulfonate solution and uniformly stirring to obtain a uniformly-dispersed mixed solution (A), (ii) adding graphene oxide dispersion liquid to the mixed solution (A) and ultrasonically dispersing to a uniform state to obtain a uniformly dispersed mixed solution (B), and (iii) taking foamed nickel as an anode, an equal-area graphite plate as a cathode and the mixed solution (B) as an electrolyte, and performing electrochemical deposition to obtain a PPy/GO composite capacitor deionization electrode material. USE - The method is useful for preparing PPy/GO composite capacitor deionization electrode material for adsorbing wastewater, preferably wastewater containing heavy metals (all claimed). ADVANTAGE - The method adopts simple process under strong repeatable operation, is suitable for mass production, significantly improves the conductivity of the electrode material while giving the electrode material more adsorption sites by the synergistic effect of GO and PPy, and improves the capacitance performance, and the adsorption and desorption performance of the electrode material.
