| Description: | Background and purpose: Hydroxylamine is a reducing agent widely used in pharmacology and industry. The respiratory system, skin, eyes, and other mucous membranes are all irritated. Therefore, while researching biological industrial processes, quantitative HXA detection is crucial. Experimental approach: This study uses ZnO nanostructures on the glassy carbon electrode (GCE) surface to develop a sensitive electrochemical sensor for hydroxylamine (HXA). The drop-casting method was used to modify the sensor. Key results: The manufactured ZnO/GCE sensor showed outstanding catalytic performance for the electrooxidation of HXA. Using differential pulse voltammetry with a low limit of detection of 0.3 μM in the range of 0.5 to 470.0 μM, the ZnO/GCE demonstrated strong electrocatalytic performances toward HXA. Furthermore, in the detection of HXA, the ZnO/GCE demonstrated satisfactory repeatability and stability. |
