Photometric determination of chromium in
natural and industrial objects in the form ethylendiaminotetraacetates
Abstract
The optimum conditions of formation are
found and the chemico-analytical characteristics ethylendiaminotetraacetates
chromium(III) are determined. With use spectrophotometry the techniques of
definition chromium(III) in objects of various nature are developed. The
metrological characteristics do not concede received at use of classical methods
of the analysis, but the techniques considerably surpass them in productivity.
Key words: ethylendiaminotetraacetates,
nickel, cupper, cobalt, iron, titan, chromium, vanadium spectrophotometry
