چکیده
|
A ferrocene-derivative compound, 2,7-bis (ferrocenyl ethynyl) fluoren-9-one (2,7-bfe), was synthesized and used to construct a modified-graphene oxide nano-sheets pasteelectrode. the electro-oxidation of hydrazine at the surface of the modified electrode wasstudied using electrochemical approaches. under the optimized conditions, the square wavevoltammetric peak current of hydrazine increased linearly with hydrazine concentrations inthe range of 2.2×10-7 to 3.0×10?4 m and a detection limit of 9.8×10?8 m was obtained forhydrazine. finally this modified electrode was used for determination of hydrazine in somewater samples
