原始语种摘要: Abstract(#br)A sensitive electrochemical sensor for determination of hydroxylamine has been introduced. This sensor profits by promazine hydrochloride (PHC) as homogenous mediator and multiwall carbon nanotubes to improve the surface of carbon paste electrode as working electrode. Cyclic voltammetry (CV), linear sweep voltammetry (LSV), chronoamperometry, and differential pulse voltammetry (DPV) are used to study of the suitability of promazine hydrochloride, at the surface of multiwall carbon nanotube paste electrode (MWCNTPE), as a homogenous mediator for the electrocatalytic oxidation of hydroxylamine in aqueous solutions. Hydroxylamine hardly oxidizes at about +1.1V at the carbon paste electrode (CPE), whereas catalytically oxidizes in presence of PHC as mediator at...
