| 英文摘要 | Natural surface coatings collected from natural substances ( NSCsNS) were employed to study the roles of the main chemical components( iron oxides, manganese oxides, and other components) in controlling the adsorption of lead(Pb) and eadmium(Cd) in aquatic environments. The selective chemical extraction followed by the adsorption of Pb and Cd experiments and statistical analysis, were used to investigate the adsorption property of each component. Hydroxylamine hydrochloride was used to remove manganese oxides selectively, and sodium dithionite was used to extract iron oxides and manganese oxides. The result indicated that iron oxides and manganese oxides played an important role in the adsorption of Pb and Cd on NSCsNS, and the relative contribution was about two-thirds. The contribution of manganese oxides was the greatest, with a lesser role indicated for other components. The adsorption ability of manganese oxides for Pb and Cd was greater than that of iron oxides or other components for Pb and Cd. The Ph adsorption observed in each component was greater than Cd adsorption. |
