Biosorption of Sb(Ⅴ) by Cyanobacteria from Taihu Lake

  • 摘要: 利用富营养化湖泊的藻类——太湖蓝藻,对Sb(Ⅴ)的生物吸附特征进行了研究. 结果表明:藻类经0.1 mol/L盐酸处理后,对Sb(Ⅴ)的生物吸附效率大大提高. 原藻和经盐酸处理的蓝藻在1 h左右对Sb(Ⅴ)的吸附量达到平衡;Sb(Ⅴ)在原藻和经盐酸处理的蓝藻表面的吸附能力均随着pH升高逐渐减弱;原藻与经盐酸处理的蓝藻对Sb(Ⅴ)的吸附等温线符合Freundlich方程;不同离子强度的Cl-、NO3-、SO42-、PO43-对Sb(Ⅴ)在原藻表面的吸附影响较弱,而对Sb(Ⅴ)在经盐酸处理的蓝藻表面的吸附影响显著.
