After digestion, the measurements were
carried out with an atomic
fluorescence spectrometer (AFS) model
Millennium Merlin instrument PSA 10.025 (Orpington, UK) in the
range of 0.025 to 0.2 ng mL1 Hg(II). The
flow rates were adjusted at
9 mL min1 for the carrier and sample and to 4.5 mL min1 for the
reducing agent.
