“…This water-soluble vic-dioxime later proved to be a very sensitive qualitative reagent for these ions. Its solubility in water was found to be 8.2 gram (o.o58 mole) per liter at room temperature (42,90) or 17 times greater than the corresponding molar solubility of 2,3-butanedionedioxime and l,2-bis(2-furyl)ethanedionedioxime.…”

The need for a water-soluble vic-dioxime as an analytical reagent for nickel(II) and palladium(II) ions has long been evident. Thus, a preparation and investigation of some alicyclic vic-dioximes as possible watersoluble reagents was undertaken. Secondly, in order to obtain a better understanding of the structure of the inner-complex compounds that the vic-dioximes form with certain ions, an infrared spectroscopic study of the nature of the hydrogen bonds in these inner-complex compounds was made.

“…Dimethylglyoxime is usually used for this precipitation, but nioxime (1,2-cyclohexanedione dioxime) is more popular simply due to its solubility in water, as shown in Scheme 1. 17 For an appropriate choice of condition, the conjugation system generates a pink color change, so great effort has gone into the colorimetric or spectrometric detection of this pink precipitation. Colorimetric solid phase extraction has been proved a successful method to detect this precipitation, 18 the low loading capacity of the chelate reagents, however, limits the sensitivity.…”

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.

BANKS, AND HARVEY DIEHL The Institute for Atomic Research and the Department of Chemistry, Iowa State College, Ames, Iowa THE preparation of 1,2-cyclohexanedione dioxime, nioxime, and its use in the analytical chemistry of nickel have been reported (1,4). Nioxime also yields an insoluble yellow compound with palladium -which can be used for the detection and determination of this metal.…”

“…The color was lighter than (1) and under the knife the sample was soft and plastic. (4) This sample (1937) was closely similar to (3) but differed in the stated analysis-i.e., "non H2S substance-0.40, acid-insoluble-0.10, H2S metals (not Pb)-0.02, Fe-0.005, Mn-0.003, SO,-0.002, COs-0.003, NOa-0.005, Cl-0.0015, and PbO;-91.4%." Total assay was 91.94%.…”
