摘要

The electrochemical activities of hydroxylamine (HX) as a pollutant compound at a 1,1- bis(phenylacetyl)ferrocenele/NiO/CNTs modified carbon paste electrode (1,1-BPF/NiO/CNTs/CPE)has been studied. 1,1-BPF was used as a suitable mediator for elecrocatalytic interaction with HX. Thevoltammetric properties of HX at the 1,1-BPF/NiO/CNTs/CPE was investigated by cyclic voltammetry(CV), electrochemical impedance spectroscopy (EIS), chronoamperometry, and square wavevoltammetry (SWV) methods. The oxidation peak current increases linearly with HX concentration inthe range 0.550.0 M and the detection limit for HX was 0.2 M. The sensor was applied towastewater samples with excellent performance.
