NOVELTY - The utility model claims a fast detecting trace heavy metal ion electrochemical probe, comprising more than 2 glassy carbon electrode, the glassy carbon electrode detecting the graphene film surface and a conductive wire electrically connected with the glassy carbon electrode. the glassy carbon electrode are fixed in the insulating shell, two adjacent glassy carbon electrode by insulating detection surface of the shell separation, glassy carbon electrode at the bottom and/or side face of the insulating shell fast detecting trace heavy metal ion; the utility model claims an electrochemical probe. the common glassy carbon electrode for surface detection is uniformly attached to a graphene film, graphene with high specific surface area, strong absorbing ability and good conductive performance, and obviously improves the Cd2 +, Pb2 +, electrochemical dissolution peak signal, finally realize the detection of Cd2 +, Pb2 + of high sensitivity and fast detecting speed, setting a plurality of glassy carbon electrode and space position of each carbon electrode is different, greatly improves the detection precision and detection range.
