| description | An optimization procedure was developed in this study using Competitive Ligand Exchange-Adsorptive
Cathodic Stripping Voltammetry (CLE-AdCSV) to determine the concentration of dissolved Fe(III) in
coastal water collected at Pulau Redang, Terengganu. The method was optimized for the UV-irradiation
period for dissolved organic digestion, while the pH of the samples prior to UV-irradiation was
determined. Additionally, the types and concentrations of the artificial ligands, followed by the sample
equilibration period for sample measurements, were confirmed and performed. A small standard
deviation of 0.002 was obtained in this experiment, indicating that the data obtained were precise when
the optimized method was applied. Those optimized method was applied to the samples at Station 3, and
the data obtained were compared with the previous study. Our present data showed that the concentration
of dissolved Fe(III) was low, approximately 6 - 82 times lower than previously reported data. As our
study area was affected by the Northeast monsoon (NEM), the phenomenon of strong turbulence during
the post-monsoon event could have caused the resuspension of bottom sediment to the upper layer of
seawater. Hence, the total suspended solids (TSS) level could have increased in the water column,
suggesting that Fe(III) was mainly attached to the particulate phase rather than during the dissolved
phase. |
