▎ 摘　　要

A ferrocene-derivative compound, 2, 7-bis (ferrocenyl ethynyl) fluoren-9-one (2,7-BFE), was synthesized and used to construct a modified graphene paste electrode. The electrooxidation of hydroxylamine at the surface of the modified electrode was studied using cyclic voltammetry (CV), chronoamperometry (CHA), and square wave voltammetry (SWV). Under the optimized conditions, the square wave voltammetric peak current of hydroxylamine increased linearly with hydroxylamine concentration in the range of 2.0 x 10(-7) to 2.5 x 10(-4) M and detection limit of 9.0 x 10(-8) M was obtained for hydroxylamine. Finally, this modified electrode was used for determination of hydroxylamine in some water samples.
