摘要

The current study deals with the sensitive electrochemical sensor for ecologically harmful p- Nitrophenol (pNP) based on a glassy carbon electrode which was modified by nickel-curcumin[Ni(Curc)2]/graphene oxide [GO]. The physicochemical properties of the as-prepared nanocompositeswere characterized using a different analytical and spectroscopic method, which include UV-Visspectrophotometer, fourier-transform infra-red spectrophotometer, field emission scanning electronmicroscopy and cyclic voltammetry. The reduction of pNP at modified GCE revealed linear range-1 2 0.49-760 M, limit of detection 0.016 M and high sensitivity 0.671A M cm . The recommendedsensor was well developed and established the influence of low cost, easily prepare, which is greater tonewly reported modified electrodes, thereby permissive practical industrial applications.
