摘　　要：如今处理重金属废水的方法很多,如:生物吸附法、化学法、离子交换法、溶剂萃取法、膜分离法等。其中,生物吸附法作为一种新兴的处理技术,在处理低浓度的重金属废水方面有着广阔的应用前景。与传统的处理方法相比,生物吸附法的原材料成本和操作费用较低,并且在处理过程中,实验条件比较宽泛。本论文是以香蕉皮和香蕉叶为吸附材料,对重金属镉进行吸附。通过考查温度、pH值、吸附时间、初始浓度、吸附剂的使用量等因素来探讨吸附材料对重金属镉的最佳吸附条件。Nowadays, many methods were employed to treat the heavy metal wastewater, such as biosorption process, chemical method, ion exchange method, olvent extraction method, and separation membrane. As one of the developing methods, biosorption process presented a widely application in treating the heavy metal wastewater with low concentration. Compared with traditional methods, biosorption process exhibited less cost for the raw materials, less charge for operation, and more broad experimental conditions. Banana peels and banana leaves were used as the adsorp- tion material to treat cadmium wastewater with low concentration. The best condition of treating cadmium, the influencing factors, such as temperature, pH values, adsorption time, initial concentration, and focused on and discussed. dosage of adsorption materials were
