▎ 摘　　要

NOVELTY - Water heavy metal ion detecting and recycling electrode comprises a polyimide carving substrate (1) and laser engraving graphene film (2) is formed by scanning along the surface of polyimide engraving substrate by a laser engraving machine with a laser power of 10.2 W. The copper core of which is exposed at the end, spreads out and spreads out on the surface of the laser-engraved graphene film (2), and the surface of the copper core is sealed by the hot-melt adhesive (4) and fixedly adhered to the laser-engraved graphene film. USE - Water heavy metal ion detecting and recycling electrode used for mass production, recycling, and can obtain the heavy metal material enriched in electrode surface by simple processing. ADVANTAGE - The electrode has high sensitivity, low detection limit, fast, easy to be automated, and can realize multiple heavy metal detection. The good conductivity graphene film can improve the detection efficiency, effectively reduce the time for detecting the needed time, preventing the detection precision is not accurate caused by too long time. The electrode preparation is simple and cheap in process, can be used for mass production, recycling, and obtains the heavy metal material enriched in electrode surface by simple processing. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparing the water heavy metal ion detection and recovery electrode. Method for detecting and recycling water heavy metal ion. DESCRIPTION OF DRAWING(S) - The drawing shows a water heavy metal ion detecting and recycling electrode. 1Represents polyimide carving substrate 2Laser engraving graphene film 3Represents lead 4Represents hot melt adhesive
