A nano-structured Ni(II)–baicalein(BA) film is electrodeposited on a multiwall carbon nanotube paste electrode in alkaline solution. The modified electrode shows electrocatalytic activity toward the oxidation of hydroxylamine. Kinetic parameters such as the electron transfer coefficient α, rate constant ks of the electrode reaction and the catalytic rate constant kcat of the catalytic reaction are determined. The catalytic currents present linear dependence on the concentration of hydroxylamine from 2.5×10-6 mol•L-1 to 4.0×10-4 mol•L-1 by amperometry. The detection limit and sensitivity are 6.0×10-7 mol•L-1 and 31.2 mA•L•mol-1, respectively. The modified electrode has been applied to determine hydroxylamine in water samples with satisfactory results.
