摘要：
The electrochemical behaviour of hydroxylamine at a modified screen-printed electrode with TiO2/graphene oxide (GO/TiO2/SPE) was investigated by cyclic and differential pulse voltammetry. EDS, SEM and XRD methods were implemented to characterise the nanocomposite. The hydroxylamine diffusion coefficient (D) was predicted via chronoamperometry. Moreover, the detection limit, current sensitivity and linear range for hydroxylamine were assessed via differential pulse voltammetry (DPV). The linear range and detection limit were 0.1-300 and 0.065 mu M, respectively. Additionally, the sensor exhibited exceptional stability, reproducibility, selectivity and sensitivity traits. The recommended electrode was implemented to determine hydroxylamine within water specimens entailing satisfactory results.
