Keywords: Atomic absorption spectrometry, flame atomization, electrothemal atomization, interferent effects, mechanism of modifier action, sample pretreatment, evaluation of analytical signals.

Research profile:

Preparation of new analytical methods by atomic absorption spectrometry. Study of the evaporation and atomization processes in graphite tube and the mechanisms of modifier action. Direct pretreatment of analytical samples in the graphite tube, e.g. mineralization of organic matrices, elimination of chlorides and sulphates. Preliminary preparation of samples, e.g. preconcentration, separation including speciation analysis. Study of the methods of evaluation of analytical signals obtained in the presence of interferents including the extrapolation methods.

Domains of applications:

Nuclear materials, environmental samples, mineral waters and saline waters.
