Sensitive, specific, stable, water-soluble reagents are needed for rapid, spectrophotometric determinations of trace impurities in water. Syntheses, purifications, and characterizations of the naphthol-mono-sulfonic acids are described. Data essential to the quantitative evaluation of various naphtholsulfonic acids is presented. A new method for the determination of nitrate in water is described using 2-nitroso-1-naphthol-4-sulfonic acid. A new reagent, sodium 2-nitroso-1-naphthol-5-sulfonate, has been proposed for the rapid, specific, sensitive determination of cobalt in natural waters. The method can readily be applied to such diverse systems as lakes where agricultural fertilizer run-off may be significant, to effluents from plants in the metallurgical industry, to natural-water systems in highly mineralized areas, and to run-off from strip-mined lands. Effective new research areas are identified. (Author)
