▎ 摘 要
NOVELTY - Preparation of reactive electrochemical cathode film involves dissolving graphene and organic polymer in organic solvent to obtain blend casting solution, coating into polyacrylonitrile-based carbon fiber cloth base to obtain composite membrane, soaking in strong alkaline solution for 3-12 hours and iron solution for 4-24 hours to chelate graphene, and applying voltage potential of 0.5-1 V to reduced iron (III) to iron (II). USE - Method for preparing reactive electrochemical cathode film (claimed). ADVANTAGE - The reactive electrochemical cathode film has simple preparation and has high efficiency in Fenton integrated coupling system.
