Abstract

The invention belongs to the electrochemistry and nano material technical fields, and especially relates to a graphene nano material-modified glassy carbon electrode based on phytic acid dispersion, a preparation method and an application of the electrode in detection of acetaminophen. The preparation method is as follows: graphene is dispersed in a phytic acid solution, and is subjected to ultrasonic treatment for 4-8 h to obtain a phytic acid dispersion liquid of graphene; a clean glassy carbon electrode is soaked in the phytic acid dispersion liquid of graphene, subjected to self-assembly for 1-4 h, washed and dried; the mass concentration of the phytic acid solution is 30-60%. The glassy carbon has advantages of electrode low preparation cost, simple preparation method and environment protection. The glassy carbon electrode can be applied to detection of acetaminophen, and has good electrocatalytic oxidation activity to detection of acetaminophen. The glassy carbon electrode is advantaged by fast response time, wild linearity range, good reproducibility high stability and freedom from interference of coexisting electroactive substances.

Description

technical field

[0001] The invention belongs to the technical field of electrochemistry and nanometer materials, and in particular relates to a glassy carbon electrode modified by phytic acid-dispersed graphene nanomaterials, a preparation method thereof, and the use of the electrode for the detection of acetaminophen. Background technique

[0002] Graphene is made of sp 2 The monolayer planar graphite, which is bonded by hybrid carbon atoms and has a hexagonal lattice honeycomb two-dimensional structure, is favored by researchers because of its unique structure, high mechanical strength, tunable optical properties and electrical conductivity. Graphene has been used in many fields: such as sensors, capacitors and fuel cells. However, in practical applications, graphene sheets are prone to agglomeration, which greatly affects the application of graphene. Therefore, organic solvents or aqueous surfactant solutions are usually used as graphene dispersions, relying on electrost...
