Abstract
Developed are projects of State Standards of Ukraine referring to determination of bromide, iodide, and nitrate ions in waters of different types. The method of determination of bromide,ions is based on registration of reflection spectra of products of bromination of phenol red, iodide ions—on the oxidation of the latter to iodine, its gas extraction to the solution of luminol and registration of chemiluminescence in the flow of carrier gas, nitrate ions—on chemiluminescence after reduction of nitrates to nitrites and gas extraction of nitrogen dioxide to the solution of luminol. The methods make it possible to determine bromide ions within the interval 0.02–0.5, iodide ions—0.006–0.5, nitrate ions—0.05–10 mg/dm3. A special attention is given to the study of interfering impact of water components and methods to remove it.
