In this research, we report the preparation of a high sensitive voltammetric sensor for electrocatalytic determination of hydroxylamine (HX) in the presence of thiosulfate (TS). We describe the synthesis and characterization of CdO nanoparticles (CdO/NPs) with transmission electron microscopy (TEM) and X‐ray diffraction (XRD) methods. At an optimum condition, the two peaks are separated ca. 0.58 and 0.92 V for HX and TS at the surface of the proposed sensor. Square wave voltammetry (SWV) of HX exhibited two linear dynamic ranges with a detection limit (3 σ ) of 0.06 µmol L −1 . The propose sensor was used for determination of HX in water samples.
