Application of radiotracers to methodological studies in atomic absorption spectrometry. Invited lecture
Abstract
The capabilities and applicability of the radiotracer technique for methodological studies in hydride generation and electrothermal atomic absorption spectrometry are discussed and demonstrated by using several selected examples. It is shown that, for studying chemical and physico-chemical aspects of atomic absorption spectrometric methods, the radiotracer technique is superior to other techniques, including atomic absorption spectrometry itself. A number of special problems associated with fundamental phenomena or error diagnosis can be clarified and/or solved exclusively by means of the radiotracers. Therefore, the more frequent use of radiotracers in investigations aimed at improving the accuracy of atomic absorption spectrometric methods would be beneficial.
