摘要: The field of selenium speciation has been studied for decades and the growing interest in this seems never to reach a plateau. Although powerful techniques based on mass spectrometry are nowadays used determination/speciation, few laboratories can support high cost such techniques. hyphenation chromatography atomic absorption or fluorescence (AAS AFS) is still reliable low-cost alternative routine laboratories. In work we present most important parameters dealing with along latest trends subject, namely items related sample treatment AAS AFS detection.
