Detection of Hydrazine Hydrate Based on Thermally Reduced Graphene
Thermoreduced graphene was prepared using high-temperature annealing technology,and the structure and morphology of the graphene material were characterized by SEM.The drop coating method was used to modify graphene suspension on the surface of glassy carbon electrode.The electrochemical behavior of hydrazine hydrate molecules at the interface of graphene electrode was studied.The cyclic voltammetry(CV)test results indicate that hydrazine hydrate can undergo rapid electrocatalytic oxidation reaction on the elec-trode.Compared with the bare glassy carbon electrode,the graphene electrode greatly improves the electrocatalytic oxidation activity of hydrazine hydrate.Under optimized experimental conditions,oxidation peak current of hydrazine hydrate shows a good linear relation-ship with its concentration in the range of 1×10-4-1.1×10-3 mol·L-1(R2=0.993 6).This graphene electrode is expected to be used for sensitive and rapid detection of hydrazine hydrate samples in practical life.
