Efficient analysis of polycyclic aromatic hydrocarbons by dispersive-μ-solid-phase extraction using silica-based nanostructured sorbent phases coupled to gas chromatography-mass spectrometry
(2023) [Artigo de periódico]In this study, SBA-15 mesoporous silica has been investigated as sorbent phase for the extraction and determi nation of 10 polycyclic aromatic hydrocarbons (PAHs) in environmental water samples for the first time. The ... -
Polycyclic aromatic hydrocarbons in Antarctic ice core : prior study by homogeneous liquid-liquid extraction and high-performance liquid chromatography
(2022) [Artigo de periódico]Organic contamination has been less investigated in Antarctic snow and ice than in other matrices due to analytical operational problems. In this study, the concentration of 14 Polycyclic Aromatic Hydrocarbons was determined ...
