| Abstract: | The optimal formation conditions have been found and the chemical analytical characteristics have been determined for ethylenediaminetetraacetates of chromium(III). The techniques for the photometric determination of large amounts of chromium in chromium ore, alloyed steel, ferrochromium, and chromium(III) oxide have been developed. The metrological characteristics are not inferior to those obtained using conventional methods of analysis, but surpass them with respect to output. |
