Abstract
A simple and cheap procedure for solid composite electrode fabrication is described, including the pressure casting of carbon black and polyethylene (CB/PE) concentrate (30:70 mass), which is industrially produced (known as masterbatch) and commercially available. The gold microelectrode ensemble (Au-MEE) was obtained by electrodeposition of Au on the mentioned composite electrode. The Au-MEE based on the described CB/PE composite substrate demonstrated better sensitivity, reproducibility and stability in time than other widely used carbon-based substrates. Analytical possibility to perform voltammetric determination of the trace As, Hg, Se, Fe, Cr, NO 2-ions at CB/PE based gold electrode is shown.
