摘要
研究了废弃物基活性炭对挥发性有机污染物中的典型组分——甲苯的吸附特性。结果表明,废弃物基活性炭吸附甲苯等温线的类型系优惠型吸附等温线,表明具有良好的吸附能力;同时其吸附甲苯时穿透时间的对数与甲苯入口浓度的对数之间具有良好的线性相关性,即可由吸附高浓度甲苯时的穿透时间估算低浓度时的穿透时间;动态吸附时废弃物基活性炭的中孔对甲苯亦具有一定的吸附性能。
The adsorption property of waste-based activated carbon（WAC） to toluene, one kind of typical volatile organic compounds（VOCs）, was studied. The results indicate that the adsorption isotherm of WAC to toluene is the optimal adsorption isotherm, that is,WAC has strong adsorption ability for toluene. There is linear relationship between the logarithm of the breakthrough time of adsorption of WAC to toluene and that of the inlet concentration, so the breakthrough time at low concentration can be estimated from that at high concentration. The mesopore of WAC has certain adsorption ability to toluene in the process of dynamic adsorption.
