Abstract

Abstract: Selective extraction techniques followed by adsorption experiment and statistical analysis were applied to investigate the relative adsorption contribution of different components of suspended particulate for Pb and Cu and direct extraction method was employed to study the enrichment characteristic of suspended particulate. By comparison of adsorption characteristic and enrichment characteristic, the roles of main components of suspended particulate for Pb and Cu adsorption onto suspended particulate were confirmed. The results indicate that the adsorption characteristic of components was comparable to enrichment characteristic of them. Pb tends to bind with Fe oxides. Organic materials were most important adsorbents for Cu adsorption and enrichment.
