摘要
关于水污染的话题不断被提起,特别是工农业废水及生活污水对水体的污染,其给生态系统和人类健康带来日益严重的污染和危害。如何快速高效的去除废水中的污染物是当前烝待解决的问题。近年来,通过静电纺丝技术制备的纳米纤维材料具有大的比表面积、高的孔隙率、极好的孔连通性、容易改性、制备简单、成本低廉等优点,使其成为一种吸附废水中污染物的优良吸附剂材料。为了进一步提高电纺纤维对水体中污染物的吸附能力,对纤维进行特定的功能化可以实现其对水中污染物的良好吸附去除。本文介绍了我们制备的几种不同类型功能化的纳米纤维吸附剂材料,通过接枝改性、原位共混电纺、水热表面改性等方法来实现静电纺纳米纤维的功能化,并研究了它们对于工农业废水中常见的污染物重金属离子、染料、除草剂等的吸附性能。
The topic of water pollution has been always brought up and the water pollution has brought serious pollution and harm to the ecosystem and human health.How fast and efficient removal of pollutants in wastewater is regarded as the most serious problems.In recent years,nanofibers which prepared by electrospinning technology have large specific surface area,high porosity,excellent pore connectivity,easy to change,simple preparation,low cost and other advantages,making them become excellent adsorbent materials in wastewater pollutants.This paper presents several different types of functional nanofiber adsorption material.We realize the function of nanofibers by grafting modified,in-situ blend electrospinning and hydrothermal surface modification methods and study their adsorption properties for heavy metal ions,dyes,and herbicides.
