Abstract : This paper demonstrates the use of electrospinning technology to fabricate fly ash composite fibrous membranes for adsorption of volatile organic compounds (VOCs)from air. VOCs as one of air pollutants,are mainly from the painting industries, plastics industries, chemical industries and fossil fuel combustion industries,which form a serious threat to human health and ecological environment. Fly ash (FA), a by-product of coal-fired power stations, has large specific surface area and pore structure, and has been widely used in building materials and some adsorbent materials. In this paper, various weight ratios (0/1, 1/5, 2/5, 3/5, 4/5 and 5/5) of FA and polyacrylonitrile (PAN) were successfully fabricated into composite fiber membranes, respectively.Their binding properties were investigated by field emission scanning electron microscopy (FE-SEM), biological transmission electron microscopy (Bio-TEM), X-raydiffraction (XRD) and other experimental analyzers. The results show that 2/5 ratio of electrospun fly ash composite fiber membrane has the highest VOCs adsorption capacity compared with other ratios of membranes, because it has the smallest fiber diameter (283 nm) and the largest BET surface area (13 m2/g) compared with other membranes. In addition, all electrospunFA composite membranes have significantly effected for adsorption of xylene, follow by toluene and benzene.FA as a pollutant adsorbent, can not only reduce the environmental pollution caused by FA, but also control other environmental pollutants.Especially in the form of fiber membrane, it will greatly increase its application fieldfor controlling environment pollution. Suchas an air filter. Indexterms - Environment pollution, Fly ash, volatile organic compounds, Electrospinning technology, Air filter.
