Atomic emission analysis in the ac arc of heavy metals in deposits of petrochemical industries

Environmental pollution with heavy metals is one of the most pressing problems, due to a wide range of negative effects of heavy metals, including a detrimental effect on vegetation, soil, as well as degradation of the ecosystem as a whole. Sources of heavy metals pollution are mining and ferrous metallurgy enterprises, petrochemical plants, machine-building plants. Determination of the content and concentration of heavy metals in the current environmental situation is more than relevant for assessing the quality of the environment. Currently, there are two main groups of analytical methods for the determination of heavy metals: electrochemical and spectrometric methods. Atomic emission analysis in an alternating current arc is a powerful method of qualitative analysis of heavy metals in deposits of petrochemical industries, thanks to the ability to simultaneously determine directly in powder up to 70 macro- and microelements with detection limits up to millionths. As part of this work, patent studies were conducted to determine the technical level and identify scientific and technical developments.
