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。
Fossil fuel combustion produces some gases that are harmful to humans and the environment. One of the ways to control the emission of these pollutants is through the use of nanoparticle adsorption. In a recent study, nano-gamma alumina particles were added to polyacrylonitrile polymers by a simple loading method and the adsorption capacity of the fibers prepared by wet spinning was investigated. The results show that the polyacrylonitrile fibers with nano-particles show better sorption capacity for acidic gases including SO2, CO, NO2, NO and CO2.
