摘要: 利用长春南湖水培养生物膜, 研究自然水体生物膜上铁氧化物的含量变化对生物 膜吸附镉动力学、 热力学的影响. 结果表明, 在自然水体生物膜吸附镉的过程中, 生物 膜对镉的吸附随生物膜上铁氧化物的含量呈规律性变化.

关键词: 自然水体生物膜, 铁氧化物, 镉, 吸附

Abstract: The adsorption of natural surface coatings, developed in the Nanhu Lake(Ch angchun, China), towards Cd was studied to determine the effects of the amounts of Fe oxides in surface coatings on Cd adsorption and the dyn amics and thermodynamic characteristics of Cd adsorption. The results indicate that the amounts of Fe oxides influence Cd adsorption to natural surface coating s greatly.

Key words: natural water surface coatings, Fe oxides, cadmium, adsorption
