| Abstract: | Systematic investigations of the influence of the elemental composition and concentration of surfactants on the atomic absorption
of chromium have been carried out. It is shown that sodium dodecyl sulfate maximally increases the analytical signal and selectivity
in chromium determination. The atomic-absorption technique of determining the quantitative content of chromium in sewage of
industrial enterprises with application of sodium dodecyl sulfate as a chemical modifier has been developed. The detection
limit for chromium is 1.2 μg/dm3.
