A procedure involving catalytic oxidation of sulphones has also been developed218. In this case the sulphone is mixed with sodium carbonate and cobalt(II) oxide and the mixture is burned in a stream of oxygen. This method works very well for nitrogen-containing sulphones and requires no expensive equipment. 

The flow-cell design was introduced by Stieg and Nieman [166] in 1978 for analytical uses of CL. Burguera and Townshend [167] used the CL emission produced by the oxidation of alkylamines by benzoyl peroxide to determine aliphatic secondary and tertiary amines in chloroform or acetone. They tested various coiled flow cells for monitoring the CL emission produced by the cobalt-catalyzed oxidation of luminol by hydrogen peroxide and the fluorescein-sensitized oxidation of sulfide by sodium hypochlorite [168], Rule and Seitz [169] reported one of the first applications of flow injection analysis (FTA) in the CL detection of peroxide with luminol in the presence of a copper ion catalyst. They... 

Ammonia is determined by the Kjeldahl method. Cobalt is determined by decomposing the salt with aqueous sodium hydroxide, dissolving the cobalt(III) oxide in acidified potassium iodide, and titrating the liberated iodine with thiosulfate. Anal.

In most of its ionic compounds, cobalt is either Co(II) or Co(III). One such compound, containing chloride ion and waters of hydration, was analyzed, and the following results were obtained. A 0.256-g sample of the compound was dissolved in water, and excess silver nitrate was added. The silver chloride was filtered, dried, and weighed, and it had a mass of 0.308 g. A second sample of 0.416 g of the compound was dissolved in water, and an excess of sodium hydroxide was added. The hydroxide salt was filtered and heated in a flame, forming cobalt(III) oxide. The mass of the cobalt(III) oxide formed was 0.145 g.

Klissurski et al. [87] have examined the combustion of acetone, toluene and styrene by zinc-cobalt spinel oxides supported on alumina. Catalysts were prepared by co-precipitation with sodium carbonate from a mixed zinc/cobalt nitrate solution at pH 9. The supported catalyst was prepared by deposition of the precursor on Y-AI2O3 from a suspension in dimethylformamide and water. The supported precursor was dried at 150°C and calcined at 300°C to produce the catalyst. The bulk and supported catalysts both showed the formation of zinc cobaltite spinel structures which were thermally stable. Microreactor studies at 15,000 h- space velocity showed that the components of a mix of acetone, toluene and styrene were destroyed at 225°C, 280°C and 350°C respectively. The VOC concentrations were not specifically expressed but it is assumed that they... 

According to Baier (2001), the ABLR yields the same mass transfer performance (defined as oxygen transfer rate obtained by cobalt-catalyzed oxidation of sodium sulfite) at half the power input as compared to the conventional BLR.

Homs et al. reported that nickel supported on zinc oxide is not a favourable catalyst formulation for ethanol steam reforming, but the addition of nickel to a cobalt/zinc oxide catalyst promoted with sodium increased the catalytic activity [206]. At S/C 6.5 and only 300 °C reaction temperature, full ethanol conversion could be achieved without by-product formation, apart from methane. 

This pigment is described by Riffault et al. (1874) as a combination of aluminium oxide and cobalt oxide. It is prepared by faking an alum solution and dissolving in it cobalt nitrate, sulfate or chloride. A pink-white precipitate is formed with sodium or potassium carbonate the product is then washed, dried and calcined in a crucible at high temperature. It would consequently appear to be a manufacturing variant of cobalt aluminium oxide (that is, cobalt blue ) and is also stated to be synonymous with Gahn s ultramarine qq.v.).
