摘要
柑橘皮价格低廉,来源广泛,材料易得,皮中含有丰富的多糖类高分子化合物和木质素,可提供官能团与金属离子结合,去除重金属效果好,可用作制备生物吸附剂。如今工业废水污染严重,重金属污染物在环境中稳定,难去除,生物吸附剂对废水溶液重金属离子具有良好的吸附性能,本文收集了国内外学者利用柑橘皮制作生物吸附剂的资料,综述了改性柑橘皮用于吸附废水中重金属处理的研究进展。
Citrus peel is cheap, widely sourced and easy to obtain. It contains rich polysaccharides, macromolecule compounds and lignin. It can provide functional groups and metal ions to bind and re-move heavy metals.It can be used to prepare biological adsorbents. Nowadays, industrial wastewater isseriously polluted. Heavy metal pollutants are stable in the environment and difficult to remove. Adsor-bents have good adsorption performance for heavy metal ions in waste-water solution.this text collects the data of domestic and foreign scholars using citrus peel to produce adsorbents, and summarizes the research progress of modified citrus peel for heavy metal adsorption in wastewater treatment.
