| 摘 要： | 研究了自然水体生物膜及其主要组分吸附铅和镉时共存铅、镉间的相互影响,结果发现共存的镉对生物膜各组分吸附铅的能力影响很小,而共存的铅使各组分吸附镉的能力明显下降,且不同组分受影响的程度比较接近.

| Abstract: | The influences between Pb and Cd when they were adsorbed simultaneously by natural surface coatings and their components, including Fe oxides, Mn oxides and organic matters etc. , were studied using selective extraction method. The results showed that compared with unitary adsorption system, the accompaniment Cd had only a little effect on Pb adsorption to each component, while the accompaniment Pb reduced the adsorption of Cd to these components significantly and these reduction effects were similar to each component. |
