Abstract:
The energies of the chemisorption of As, Se, Pb, and Cd atoms by palladium and cobalt metal surfaces were calculated by a quantum chemistry method. The analytical applicability of a cobalt-containing chemical modifier based on activated carbon to the determination of the highly volatile elements by electrothermal atomic absorption spectrometry (ETAAS) was hypothesized. A procedure for the preparation of the cobalt-containing chemical modifier based on activated carbon was substantiated using thermodynamic simulation, thermal analysis, and ETAAS. This procedure ensured the formation of a Co0 metal phase and the occurrence of thermal stabilizing interactions with analytes at the stage of drying. The concentrations of arsenic and lead in the suspensions of a standard reference sample of marine algae were determined with the use of the developed chemical modifier based on activated carbon. The experimental results were consistent with the certified values
