A reagent-free fully automated flow injection analysis (FIA) system coupled to atomic fluorescence spectrometry (AFS) for mercury (Hg) quantification is reported, using active nano-structured gold collectors for direct preconcentration of dissolved mercury species from natural waters. Recently we had shown the potential of such an approach for Hg analysis in seawater. This paper now describes the optimisation and validation of the proposed method including the investigation of possible… CONTINUE READING
