| 摘 要： | 本文采用一套连续浸提程序,对珠江口海区七个有代表性采样站的悬浮物不同地球化学相中金属元素分别浸取,并作含量测定,分开的地球化学相有6个:离子交换和吸附、碳酸盐、易还原、可还原、有机物和硫化物、残渣相等;测定的元素包括Al、Fe、Mn、Ti、Cu、Pb、Zn、Cr、Co和Ni等。研究结果成功地用于说明在连续变化的河口中,颗粒金属元素的化学行为,与环境的作用机制,相分配,阳相变化;成功地用于说明颗粒金属地球化学、河口化学连续变化过程。

| Abstract: | Using a sequential extraction procedurr, the metal elements were partitioned in different geochemical phasee of suspended paniculate matter collected from 7 repre-sentive sampling locations in the estuary of the Zhujiang River(the Pearl River), and their contents were determined. There were 6 phases divided:ion-exchange and adsorption, carbonates, easy of reducing, reducihleness, organic matter and sulfides, and residual. Ten metals(Al, Fe, Mn, Ti, Cu, Co, Pb, Zn, Cr and Ni) in the estuarine chemical processes have been investigated. The results successfully reflect distribution, behavior, removal and variation of various phase elements of the suspended matter in the complicated estuary. |
