摘要
The current study deals with the sensitive electrochemical sensor for ecologically harmful pNitrophenol (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 nanocomposites were characterized using a different analytical and spectroscopic method, which include UV-Vis spectrophotometer, fourier-transform infra -red spectrophotometer, field emission scanning electron microscopy and cyclic voltammetry. The reduction of pNP at modified GCE revealed linear range 0.49-760 mu M, limit of detection 0.016 mu M and high sensitivity 0.671 mu A mu M-1 cm(2). The recommended sensor was well developed and established the influence of low cost, easily prepare, which is greater to newly reported modified electrodes, thereby permissive practical industrial applications.
