Application of Microwave Plasma Atomic Emission Spectrometry and Hydride Generation for Determination of Arsenic and Selenium in Mineral Water

Resumo

The ability to determine arsenic and selenium at their maximum acceptable concentrations (MAC) in drinking water via microwave plasma atomic emission spectrometry (MP-AES) and hydride generation is shown in this study. The determination of these elements is possible even in samples with a high degree of mineralization (up to 12 g/L). To provide the required sensitivity of determination of both elements, certain operating modes of the spray chamber for hydride generation are chosen. The conditions for the determination of these elements in mineral and medical-table waters are proposed.
