Analysis of incinerator waste emissions containing toxic elements by sorption–continuum source electrothermal atomic absorption spectrometry

Abstract

Possibilities of the determination of toxic elements, As, Cd, Co, Cr, Cu, Ni, Pb, Se, Sn, and Te, in emissions from a waste incineration plant are studied by high-resolution electrothermal atomic absorption spectrometry of with a continuum spectral source. A procedure is developed for the preparation of samples of solid domestic waste by the sorption of toxic elements on an S,N-containing sorbent. The analytical conditions of work on an atomic absorption spectrometer with a continuum spectral source are chosen. An improvement of performance characteristics in comparison to the known procedures is shown. A procedure of the determination of the chosen toxic elements in emissions from an incineration plant by electrothermal atomic absorption spectrometry with improved performance characteristics is developed and passed through metrological certification.
