摘　　要：为了开发对重金属离子有很高吸附性能的生物吸附剂,文章对天然海带进行化学处理,研究了改性海带对铜离子的吸附能力。结果表明,天然海带、HCl处理后的海带及NaOH处理后的海带对铜离子的吸附量分别为59.3,38.6和88.0mg/g。化学改性提高了海带对铜离子的吸附能力,在废水处理中有很高的应用价值。To develop biosorbent materials with high absorption capacity for heavy metal ions, chemical treatment to natural seaweed and absorption of copper ions by modified seaweed were studied. Results showed that absorption capacities for copper ion were 59.3, 38.6 and 88.0mg/g respectively for natural seaweed, HCl treated seaweed and NaOH treated seaweed. Absorption capacity of seaweed was enhanced by chemical treatment, making it valuable in treatment of wastewater.
