纳米氧化铝粒子对聚丙烯腈纤维物理吸附性能的影响

Effect of nano-alumina particles on physical adsorption property of acrylia fibers

矿物燃料燃烧会产生一些对人体和环境有害的气体,控制这些污染物排放的其中一种方法是利用纳米粒子的吸附作用。在最近的研究中,通过简单负载的方法将纳米γ氧化铝粒子加入聚丙烯腈聚合物中,并研究了湿法纺丝制备的纤维的吸附能力。研究表明,添加了纳米粒子的聚丙烯腈纤维对包括SO2,CO,NO2,NO和CO2的酸性气体表现出更好的吸附能力。

The flue gas from fossil fuels combustion contains harmful pollutants dangerous for human health and environment. One of the air pollution control methods to restrict the emission of these pollutants was based on using nanoparticles in the adsorption process. In the present research, gamma nano-alumina particle was added to polyacrylonitrile （PAN） polymer through simple loading method and the adsorption capacity of the wet spun fiber was investigated. The results of exposure of the fiber to the acid gases including SO2, CO, NO2, NO and CO2 showed the noticeable increase of gas adsorption capacity on fiber contains nanoparticle.
