摘要: 利用逐级提取法分析了向海湿地水环境培养的生物膜上铁、 锰氧化物的形态, 结果表明, 不同类型水环境培养的生物膜上铁氧化物的存在形态以铁锰氧化物结合态为主 , 而锰氧化物的存在形态以有机质结合态为主, 生物膜上铁、 锰氧化物的存在形态是膜上铁氧化物吸附镉、 锰氧化物吸附铅相对吸附能力存在较大差异的原因.

关键词: 生物膜, 铁、锰氧化物, 形态, 铅、镉, 吸附

Abstract: The chemical species of the Fe and Mn oxides in the natural surface coatings, which were developed in Xianghai Wetland, were investigated via Tessie r’s sequential extraction procedure. The results show that the Fe oxides exist mainly in Fe and Mn incorporated oxides form, while the Mn oxides primarily in organic form. The resulted information obtained also indicates that the chemical species of Fe and Mn oxides in the natural surface coatings may be important factors causing the difference between the adsorption capacity of Pb onto the Mn oxides and that of Cd onto the Fe oxides in the natural surface coatings.

Key words: natural surface coating, Fe and Mn oxides, chemical species, adsorptio n
