▎ 摘　　要

NOVELTY - Preparation of reduced graphene oxide-silver aerogel surface enhanced Raman spectroscopy (SERS) substrate involves (S1) uniformly stirring graphene oxide aqueous solution and silver nitrate solution, slowly dripping triethylenetetramine as reducing agent for promoting graphene oxide and silver ion reduction to obtain mixed solution, (S2) transferring the mixed solution to hydrothermal reactor, and placing the reactor in a blast drying box, performing hydrothermal reduction self-assembly of graphene oxide and in-situ loading of silver, (S3) naturally cooling the reactor to room temperature, removing reduced graphene oxide-silver hydrogel, transferring to deionized water for aging, and (S4) pre-freezing, vacuum-freezing and drying. USE - Preparation of reduced graphene oxide-silver aerogel surface enhanced Raman spectroscopy substrate used for detecting trace fluorescence organic pollutant e.g. rhodamine 6G, 2,4,8,10-tetranitrobenzo-1,3a,6a-tetraazapentalene and pyridine (all claimed). ADVANTAGE - The method enables simple and effective preparation of reduced graphene oxide-silver aerogel surface enhanced Raman spectroscopy substrate with high sensitivity, by stable process. The reduced graphene oxide-silver aerogel surface enhanced Raman spectroscopy substrate improves detection performance of trace material to be detected. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of reduced graphene oxide-silver aerogel surface enhanced Raman spectroscopy substrate for detecting trace fluorescence organic pollutant. The detection method involves measuring the content of fluorescent organic pollutant in a detection limit of 10-7mol/L which are attached to the surface of the substrate by Raman spectrometer.
