A novel carbon paste electrode (CPE) was fabricated using 2-methoxy-6-(((3-(trimethoxysilyl) propyl) imino) methyl) phenol chemically bonded to multiwalled carbon nanotubes (MMSPIMP–MWCNTs) followed by intermixing with CuO nanoparticles, sodium tetraphenylborate (NaTPB), graphite powder, and Nujol oil. The MMSPIMP–MWCNT was characterized by Fourier transform-infrared spectro- scopy (FT-IR) and other...
A new electrochemical sensor based on screen-printed electrode (SPE) gold nanoparticles (AuNPs) has been fabricated for determination of Pb(II) ion by anodic stripping voltammetry in Tris-HCl (pH 5) solution. In this medium, Pb(II) ion was preconcentrated on SPE modified with AuNPs and stripped anodically in linear sweep voltammetry mode, with a peak potential at −0.5 V. The effect of various parameters...
