中文摘要：
重金属离子广泛存在于冶金、电镀、制革等行业排放的废水,研究者们致力于重金属离子高效吸附材料的研制已有多年,基于国内外最新研究文献,系统论述了生物质吸附材料,基于生物质吸附材料的改性产品及新型高分子的吸附性能,比较了各种吸附剂的优缺点。指出将制革产生的废弃革屑处理后得到的胶原纤维经过化学改性提高其吸附性能,原材料来源广泛。将其应用于含重金属离子废水的处理中,可以达到以废治污的目的。
英文摘要：
The heavy metal ion mainly existing in the waste water of metallurgy,electroplating and leather making industry. The researchers are focusing on high effective adsorption material. This paper based on the latest research paper,mainly discussed on the adsorption properties of biomass adsorption material,the modified product based on the biomass material and some novel macro molecular. The advantages and disadvantages of the adsorbent were compared. Collagen fibers have advantage of wide resource and it can be extracted from the abandoned waste leather shaving. After the chemical modification,the adsorption capacity of collagen fiber could be enhanced greatly. It will be of great use when used in the treatment of heavy metal ion contained waste water.
