The removal of heavy metal pollutants from industrial wastewater is important to ensure the safety of the environment and humans. In this study, rhamnolipids from Pseudomonas aeruginosa were used to treat synthetic wastewater containing Cu ions (100 mg L⁻¹) by foam separation. A high removal efficiency of 99.52 % was achieved when the somatic cells of inactivated P. aeruginosa were used as biosorbents. The analysis of the adsorption kinetics showed that dynamic biosorption followed the Langmuir isotherm model and that the bacterial cells had a strong adsorption effect on Cu ions. The novel technology based on the combination of foam separation and biosorption serves as an effective approach for the removal of Cu ions from industrial wastewater.

通过组合泡沫分离-池吸附法去除废水中的铜离子

从工业废水中去除重金属污染物对于确保环境和人类的安全具有重要意义。在这项研究中，来自铜绿假单胞菌的鼠李糖脂被用于通过泡沫分离处理含有铜离子（100 mg L ^{-1 ）的合成废水。}当使用灭活的铜绿假单胞菌的体细胞作为生物吸附剂时，去除效率高达 99.52% 。吸附动力学分析表明,动态生物吸附遵循朗缪尔等温线模型,细菌细胞对铜离子具有较强的吸附作用。基于泡沫分离和生物吸附相结合的新技术是去除工业废水中铜离子的有效途径。
