| 摘 要： | 活性炭吸附室内空气中挥发性有机化合物的１０％穿透时间与气相浓度及挥发性有机化合物的种类有关，通过对苯、甲苯和丙酮的实验研究，得出了由高浓度估算室内低浓度时炭床１０％穿透时间的经验公式ｔｂ，１＝ｔｂ，ｈ（Ｃ０，１／Ｃ０，ｈ）＾ａ，其中ａ值是与炭床性能及挥发性有机化合物种类有关的参数，可通过实验确定。 |
| 关 键 词： | 活性炭 吸附 室内空气 挥发性 有机化合物 |

| Abstract: | When volatile organic compounds (VOCs) in indoor air were adsorped by activated carbon, 10 % breakthrough time of the carbon bed was related to both the concentrations and the types of VOCs. A general emperical equation of 10 % breakthrough time expressed in t_b.1=t_b.h had been developed through the experimental study of such pollutants as benzene, methylbenzene and acetone adsorped by activated carbon, by which 10 % breakthrough time at low concentrations could be predicted from that at high concentrations. The parameter a within the equation was found to be related to the performance of activated carbon and types of VOSs, which could be determined by the experiment. |
