摘　　要：可再生、低成本、有效且易从环境获取的生物质材料越来越多地用于去除废水中的重金属离子。本文着重介绍三大类生物质材料:Ⅰ、动物类(主要是甲壳素和壳聚糖衍生物);Ⅱ、植物类(包括木质素、活性炭、竹炭、富含单宁的物质、农林废弃物等);Ⅲ、微生物类(各种菌类等),及其改性产物在处理有毒重金属废水方面的应用研究进展。The biomass materials, which are renewable and cost-effective and gained from environment easily, are more and more used in removing heavy metal ions from wastewater. The article emphasizes three sorts of biomass materiais, including： Ⅰ the animals （mainly are chitin and chitosan） ; Ⅱ the plants （including lignin, activate carbon, bamboo carbon, tannin-rich materials, agricultural and forest residues and so on ） ; Ⅲ microbiology （each fungus and so on ）, and their modified products. The utilization of such different types of biomass materials for removing some toxic heavy metal ions from water were investigated.
