“…Dowex 50 W X 12 ion exchanger for a Nujol-graphite paste base was used as a complexing agent for Ni 2+ . 4 SWV on a rotating-disk bismuthfilm electrode allowed the simultaneous voltammetric analysis of Ni 2+ and Co 2+ . The detection limit found by this procedure with DMG as a complexing agent was 1.70 ¥ 10 -7 mol L -1 .…”

“…However, in some areas, Ni 2+ concentrations may be higher because of volcanism. 4 The levels of Ni 2+ in wastewater in industrialized areas are higher than the average levels of other areas. 5 Ni 2+ is also widely found in jewels.…”

“…Square wave voltammetry (SWV) is very sensitive to a variety of trace metals on solid microelectrodes with mercury thin film. 4 It involves the complexation of trace metals with metal-specific ligands and the adsorption of the resulting complex onto the mercury surface film. 4 Since this is a surface technique, it is suitable for determining ultra-trace levels of metals in solutions such of Ni 2+ and Al 3+ using complexing agents.…”

In this contribution, the amounts of Ni (nickel) and Al (aluminum) in tilapias (Oreochromis niloticus) were determined using square wave voltammetry (SWV) with glassy carbon working microelectrode with a mercury thin film, platinum counter electrode, and Ag/AgCl reference electrode. Ni was studied through the formation of the dimethylglyoxime-Ni (Ni-DMG) complex, while Al was studied through the formation of the Alizarin R-Al complex. The detection limit found for Ni-DMG and Alizarin R-Al complexes were 1.70 ¥ 10 -7 and 1.0 ¥ 10 -8 mol L -1 , respectively. The voltammetric anodic curves for the Alizarin R-Al complex were recorded over the potential range from -0.8 to -0.05 V while the voltammetric cathodic curve for the Ni-DMG complex was recorded over the potential range from -0.7 to -1.2 V. These methods detected low concentrations of Ni and Al in biological samples efficiently.

“…6 While there are numerous methods for detecting and measuring nickel(II) and lead(II) cations, there still remains a need for an inexpensive, sensitive and highly selective analytical technology. Past analytical approaches include not only relatively expensive instrumentation (e.g., anodic stripping voltammetry (ASV), 7 inductively coupled plasma-optical emission spectrometry (ICP-OES), 8 flame atomic absorption spectrometry (FAAS), 9 graphite furnace atomic absorption spectrometry (GFAAS), 10 atomic fluorescence spectrometry(AFS), 11 etc. ), but also inexpensive colorimetric and fluorescent methods.…”

A colorimetric filtration method has been developed for the highly selective and sensitive determination of Ni 2+ and Pb 2+ ions. Determinations of Ni 2+ and Pb 2+ follow the filtration using nioxime (1,2-cyclohexanedione dioxime) and rhodizonic acid disodium salt, respectively, as colorimetric reagents. Different from regular instrumentation techniques, the metal chelate precipitations are continuously pumped into a home-made flow cell at a constant flow rate, and filtered by a cellulose acetate/nitrate membrane. The color changes of the membrane are imaged using a conventional flatbed scanner, and digitized. The special selection of individual channels in the red, green, and blue channels of the images filters the influences of coexisting ions and provides a highly selective detection of Ni 2+ and ). The determinations take five to ten minutes. No shelf life issue exists because the chelating indicators react with metal directly without any pre-immobilizations.
