全氟辛烷磺酸盐(PFOS)的吸附处理技术研究现状
|
摘要
全氟辛烷磺酸盐(PFOS)是一种新型的持久性有机污染物,具有多种毒性效应,因分布广泛和处理难度大而引起诸多关注。其特殊的疏水疏油性和高稳定性,使得其他传统水处理方法效果欠佳,而吸附处理具有低成本、高效率、易操作及吸附再生等优良性能,因此备受关注。现有大量文献研究表明,吸附剂的比表面积、表面官能团等会影响对POFS的吸附,PFOS是一种亲蛋白质的物质,金属离子可改善其吸附效果,相应的改性方法如微波改性也有利于PFOS的吸附。
Perfluorooctane sulfonate(PFOS) is a new type of persistent organic pollutant with a variety of toxicological effects, attracting much attention because of its wide distribution and handling difficulties. Its special hydrophobic and oleophobic properties and high stability, making the other traditional water treatment methods ineffective, and adsorption treatment has attracted much attention for its excellent properties such as low cost, high efficiency, easy operation and recyclable recycling. By analyzing the research of other scholars, we know that the specific surface area of sorbent, surface functional groups and so on will affect the POFS adsorption, PFOS is a pro-protein material, metal ions can improve the adsorption effect. The corresponding modification methods such as microwave Sex is also beneficial for the adsorption of PFOS.
