Herein, we report construction of a ferrocene-reduced graphene oxide-Mn spinel modified glassy carbon electrode (Fc-G/Mn3O4/GCE) as a sensitive electrochemical probe for hydrazine detectionviaits oxidation. The synergistic effect of ferrocene, graphene oxide and Mn(3)O(4)provides it a great electrocatalytic effect. The electrochemical investigations of Fc-G/Mn3O4/GCE were studied using cyclic voltammetry, while differential pulse voltammetry was utilized for recording the electrocatalytic sensing of hydrazine. The prepared Fc-G/Mn(3)O(4)offers a platform for sensitive and selective detection of low-level hydrazine in two linear ranges from 0.045 to 108 mu M and 108 to 653 mu M with limit of detection 8.5 nM. Real sample analysis was also performed in local industrial water samples with satisfactory recovery results.
