摘要

在间歇式系统中研究了一种细菌对污染水中Pb(II)和Cu(II)离子的生物吸附。从重金属污染土壤中分离得到的细菌为芽孢杆菌，确定了最佳吸附条件。在浓度低于100 mg/L的条件下，铅和铜的去除效果较好。细菌浓度也是去除重金属的重要因素。结果表明，芽孢杆菌是去除污染水体中Pb(II)和Cu(II)离子较好的生物吸附剂。

Removal of Lead and Copper Ions from Contaminated Water by Bacterial Strain

In the paper, the biosorption of Pb(II)and Cu(II) ions from contaminated water using a bacterial strain was studied in a batch system. The bacterial strain isolated from heavy metals-contaminated soil was identified as Bacillus sp. The optimum conditions of biosorption were determined. Lead and copper were removed effectively at the concentration that was lower than 100 mg/L. And the concentration of bacteria was also an important factor in removal of heavy metals. The results indicated that the strain Bacillus sp. is a suitablebiosorbent for the removal of Pb(II) and Cu(II) ions from contaminated water.
