Abstract

Sulphate-reducing bacteria isolated from submerged soil samples of paddy fields effectively precipitated copper from aqueous solution with maximum effect (75%) at 25 ppm Cu(2+). As the copper concentration was increased to 100 ppm, precipitation efficiency decreased significantly. The use of bacteria to precipitate heavy metal ions from aqueous effluents is discussed.

摘要

从稻田淹没土壤样本中分离出的硫酸盐还原菌能有效地从水溶液中沉淀铜，在 25ppmCu(2+)时效果最佳（75%）。当铜浓度增加到 100ppm 时，沉淀效率显著下降。本文讨论了利用细菌从水废水中沉淀重金属离子的问题。
