富勒烯的吸附性及其在大气挥发性有机物分析中的应用
RETENTION CHARACTERISTICS OF FULLERENES AND THEIR APPLICATION FOR COLLECTING VOCs IN AMBIENT AIR
-
摘要: 富勒烯不含官能团,对挥发性有机物(VOCs)具有化学惰性,能有效地吸附VOCs,吸附VOCs气体后存放稳定,组分流失少.9种mg·1-1级VOCs在富勒烯吸附管上的吸附突破体积为14.8—48.0L·g-1,吸附-热脱附回收率在86.5—123%之间Abstract: Fullerenes are made up of carbon atoms and free of any factional group. They are catalysis-free for VOCs, and can be stored stably with little adsorbed gases lost after adsorbing VOCs. On fullerenes, the breakthrough volumes of 9 kinds of VOCs (mg·l-1) are 14.8 to 48.0 L·g-1. The recoveries of adsorption-thermaldesorption of fullerenes adsorbent tubes ranged from 86.5 to 123%.
