摘要
利用长春市内南湖水和伊通河段河水于实验室内培养生物膜 ,通过水中掺杂镉 ,研究镉在生物膜上积累的动力学过程。结果表明 ,当镉的初始浓度为 0 0 0 5mg/L时 ,镉在生物膜上的累积量呈规律性增长 ,并与膜上铁、锰氧化物的含量呈显著的相关性。
Approximately 170 L of water from Nanhu Lake and Yitonghe River(Changchun,China) have been taken as sample to develop surface coatings in the lab in order to investigate the adsorptive accumulation of Cd. The results indicate that the accumulation of Cd in the surface coatings increases regularly when the initial concentration of Cd is 0 05 mg/L. The great effects of Fe and Mn oxides on the accumulation of Cd in the developing process of natural surface coatings are observed.
