Fabrication and characterization of extrinsic electrochemically modified graphite reinforcement carbon paste electrode for selective determination of Cu(II) in trace levels
Fabrication process of MWCNTs/ZnCrFeO4 modified carbon paste electrode for electrocatalytic determination of phenazopyridine at the surface (a) CPE, and (b) MWCNTs/ZnCrFeO4 modified carbon paste electrode.
A sensitive and selective method based on a poly(alizarin yellow R)-modified carbon paste electrode (PAYR/CPE) to detect dopamine (DA) and uric acid (UA) was successfully established.
