Application of nickel as a colouring agent in cosmetics, paints, and some varieties of plastics are in the form of nickel dimethylglyoxime compound. Electroplating on other metals by using this natural substance is also a significant application of nickel.

mining low levels of palladium in most of the commercially available titanium-base al-loys. Although l-nitroso-2-naphthol is the more sensitive reagent (its molar absorptivity is 23 000 compared to 1700 for DMG), DMG merits more attention than it has received. The procedure using DMG is faster, equally precise, and conveniently covers a wider
