摘要： 研究了富勒烯烟炱对挥发性有机物(VOCs)的吸附作用.17种VOCs气体在烟炱上的比保留体积Vg20为17.4～2634L/g.富勒烯烟炱充填的吸附管对VOCs气体的吸附-热脱附回收率在40.8%～117%之间,大部分为(100±20)%.结果表明,富勒烯烟炱能够用于吸收和富集大气中痕量的VOCs

Abstract: Fullerene-extracted soots which are the by-product of producing fullerenes(C60/C70) can adsorb organic vapors efficiently. Breakthrough volumes(maximum sample volumes, Vmax)and specific retention volumes(20 ℃)of 17 VOCs(volatile organic compounds)are measured. The recoveries of adsorption/thermal desorption of Fullerene-extracted soots adsorbent tubes ranged from 40.8% to 117%, most of which are (100±20)%. Fullerene-extracted soots is cheap and can be used in environmental analysis for trapping and enriching traces of VOCs in ambient air.

Key words: Volatile organic compounds(VOCs), Adsorbent, Fullerene-extracted soots
