碩士 / 文化大學 / 應用化學系 / 85 / Speciation of Zinc,Cadmium and Lead ions in the surface water
of erhjen river,estuarine and coastal areas is studied by
differential pulse anodic stripping voltammetry (DPASV).
Colloidal and truly dissolved phases trace metals from the water
of a highly polluted estuarine and coastal environment (The
Erhjen river) have been separated by a cross-flow
ultrafiltration device.The distributions of Cadmium,Zinc and
Lead between colloid and truly solution were 17.7%~27.4% and
72.6%~82.3% ,42.1%~63.3% and 36.7%~57.9% and 29.3%~50.1% and
49.9%~70.7% respectively.Generally ,truly solution fraction was
the dominant species in water of this study .complexing
capacities were reducing from river to coastal area. The result
indicated that Erhjen river abounds with organic ligand that
reduces as it flows toward the sea,
