Abstract: Optimization of atomic absorption spectrometric determination of elements requires, first of all, the study of spectrochemical matrix effects which, in case of insufficient elimination, may cause remarkable systematic errors in evaluation of analytical concentrations. The mentioned matrix effects were studied using experimentally determined analytical calibration lines or curves of trace element lines in the presence of varying addition of main elements Ca, Fe, K, Mg, Na, and their mixtures to the individual calibration solutions of analytical elements.
