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,
