Abstract

Publications on the use of permanent modifiers (PMs) in electrothermal atomic absorption spectroscopic analysis (ETAAS) were reviewed. Modifiers of thermally stable carbides (TCs), platinum group metals (PGMs), and their mixtures were characterized. The objects analyzed most frequently with the use of permanent modifiers were described in groups: organic solutions, suspensions and solid samples, materials after acid decomposition, and natural and drinking water. The results of the physicochemical studies of new sorbent modifiers and the thermodynamic and kinetic laws of thermochemical processes with their participation were presented.
