重金属污染已成为当今最严重的环境问题之一。由于重金属在环境中的富集性和高毒性,其处理受到特别关注。吸附法是一种经济、高效处理重金属废水的方法,而天然高分子骨架材料具有成为生物质基吸附剂的潜在应用价值。详细介绍了纤维素、壳聚糖、海藻酸钠、木质素等常见天然高分子骨架材料的改性及在水中重金属吸附中的应用。
Heavy metal pollution has become one of the most serious environmental problems today.Due to the enrichment and high toxicity of heavy metals in the environment,their treatment has received special attention.Adsorption method is an economical and efficient technique for treating heavy metal wastewater,and natural polymer skeletal materials have the potential application value of becoming biomass-based adsorbents.In this paper,the modification of common natural polymer skeletal materials such as cellulose,chitosan,sodium alginate and lignin and their applications for adsorption of heavy metals in water were described in detail.
