    Abstract

    In the present study, the determination of aluminum using resonance ionization spectroscopy has been investigated. The atomization of the sample was achieved with the use of electrothermal heating in pyrolytically coated graphite in a vacuum. The atoms were excited in two resonant steps to the Rydberg state and ionized with an electric field pulse. The influence of the sample matrix on the aluminum signal and the use of matrix modifier were studied. The detection limit for aluminum determined in this work was 4 pg. Analytical results for some reference samples are presented.
