Embodiment Construction
[0023] The present invention will be described in detail below in combination with specific embodiments.
[0024] Based on the advantages of graphene, the present invention provides a simple method for synthesizing Ag-Pt-Pd-RGO at low temperature through a simple replacement reaction, and uses it as an electrochemical TNT sensor sensing material. To the best of our knowledge, there are no reports on the fabrication of this type of hybrid nanostructures and their application to TNT electrochemical detection. The composite material has good electrical conductivity, good stability and high electrocatalytic activity. Through the detection of TNT in tap water, we believe that the Ag-Pt-Pd-RGO composite detection platform can be used for TNT detection in actual water supply systems.

Abstract
The invention discloses a preparation method of an electrochemical sensor material for detecting trinitrotoluene. Graphite powder, KMnO4, H2SO4 and H3PO4 are added into H2O2; washing is performed in deionized water to obtain oxidized graphene; ultrasonic treatment is performed; polyvinylpyrrolidone, silver nitrate and sodium citrate water solution are added; reflux condensation is performed; centrifugal washing is performed in the deionized water to obtain Ag-RGO; the Ag-RGO is dispersed into the deionized water for ultrasonic treatment; H2PtCl6 solution and PdCl2 solution are added; then, centrifugal washing is performed in the deionized water; centrifugal concentration is performed to obtain the electrochemical sensor material for detecting the trinitrotoluene. The preparation method hasthe advantages that the method is simple; the used detection material equipment can be easily prepared.
Description
technical field [0001] The invention belongs to the technical field of material chemistry and relates to a method for preparing an electrochemical sensor material for detecting trinitrotoluene. Background technique [0002] TNT (2,4,6-Trinitrotoluene) is a dual-purpose compound, which has been widely used in peaceful industries and military and terrorist applications since its discovery, such as ammunition and explosives, as well as dyes, plasticizers, Manufacture of herbicides, etc. However, in addition to the well-known safety concerns, the widespread use of TNT can also have harmful effects on our environment and health. TNT is considered to be one of the most threatening and harmful chemicals. TNT pollution has serious adverse effects on the environment and human health. At the sites where TNT is manufactured, the soil and water are destroyed, and are constantly corroded and polluted. Worse, environments contaminated with TNT are difficult to remediate due to the che...
