摘要: 分析了影响小球藻吸附Cu2+,Cd2+和Zn2+三种重金属离子的主要因素,并对不同金属离子之间的吸附抑制开展了初步试验研究.结果显示,小球藻吸附重金属离子的速度快,吸附容量大,适宜的pH值在3.0-5.0之间,其吸附等温线与Freundlich方程拟合良好.另外,小球藻对Cd2+的吸附性能明显高于其它离子.由于电子云分布和轨道杂化等结构因素,三种金属离子在小球藻上的吸附选择顺序为:Cu2+＞Cd2+＞Zn2+.

Abstract: Biosorption of copper,cadmium and zinc was carried out using chlorella,and the effects of parameters such as pH and biomass concentration on the sorption were analyzed.The adsorption of heavy metals on chlorella was a fast process with a high adsorption capacity,while the adequate pH range was between 3 and 5.Besides,the sorption process were in accordance with Freundilich isotherm.Moreover,the sorption capacity of the chlorella for Cd2+ was much higher than other two ions,and the selecting sequence was Cu2+ Cd2+ Zn2+.
