NOVELTY - The vitamin B12/graphene modified epoxy resin modified electrode, involves adding vitamin B12 powder to ethanol dispersion liquid, ultrasonically mixing to obtain VB12/Graphene mixed solution, mixing with chitosan, ultrasonically dispersing to obtain a mixed solution, adding epoxy resin to the mixed solution, ultrasonically dispersing at room temperature, rotary steaming and concentrating until liquid is not flowed out, after the concentrate is cooled, adding aqueous curing agent and stirring for 15 minutes, using a coating rod to prepare a metal electrode modified epoxy resin, and uniformly coating on the surface of the metal electrode to obtain metal electrode. USE - Vitamin B12/graphene modified epoxy resin modified electrode for catalyzing dechlorination of trichloroacetic acid (claimed) in domestic drinking water disinfection, and direct catalytic electrolysis for C-Cl fracture. ADVANTAGE - The metal electrode improves the electrolytic efficiency by improving graphene ratio, has strong dechlorination target, high dechlorination efficiency, no secondary pollution, simple electrolytic device, low cost, and provides excellent process for chloro-disinfection by-product trichloroacetic acid de-chlorination. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of vitamin B12/graphene modified epoxy resin modified electrode for catalyzing dechlorination of trichloroacetic acid.
