| 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. |
