Potentiometric stripping determination of nickel at a dimethylglyoxime-containing graphite paste electrode.
Potentiometric stripping determination of nickel(II) can be performed at zero current with a graphite paste electrode chemically modified with dimethylglyoxime. Among oxidants investigated, atmospheric oxygen present in solution was selected as the best, providing sharp and reproducible analytical signals.
