Abstract
In this work, we develop an electrochemical sensor using a polypyrrole nanotubes-modified graphite screen-printed electrode (PPy NTs/GSPE) for sensing hydroxylamine. The PPy NTs/GSPE-supported sensor has an appreciable electrocatalytic performance and great stability for hydroxylamine oxidation. Compared to a bare graphite screen-printed electrode, we demonstrate that using the PPy NTs/GSPE leads to a significant reduction in the oxidation potential of hydroxylamine. The standard curve shows a linear relationship ranging from 0.005 to 290.0 mu M (R-2 = 0.9998), with a high sensitivity (0.1349 mu A/mu M) and a narrow limit of detection (LOD) of 0.001 mu M. In addition, the PPy NTs/GSPE has satisfactory outcomes for hydroxylamine detection in real specimens.
