Abstract Information :
Engineered silver nanomaterials (AgNM) have become an essential part of our daily life. Being used as antibacterial mean in numerous products such as e.g., deodorants, cleaners or sportswear, AgNM finally end up in the environment, where their behavior and fate is still widely unexplored mainly due to the lack of available analytical techniques and methodologies for their determination at trace levels in complex matrices.
In this presentation, the hyphenation of Asymmetrical Flow Field-Flow Fractionation (AF4) and Inductively-coupled Plasma Mass Spectrometry (ICP-MS) is evaluated towards its applicability for the analysis of AgNM in complex environmental water samples at environmentally relevant concentrations < µg/L. Proper AF4 method development as well as selected examples are presented and the results obtained are critically evaluated.
