| 摘 要： | 卷烟烟气中复杂化合物对大气环境的污染已经引起了全世界的关注.因此,本文以颗粒活性炭为原料,通过硝酸钙、水蒸气调控得到比表面积、微孔容量丰富且含有较高中孔率的介孔活性炭,研究了孔结构对三醋酸甘油酯和挥发性有机物吸附的影响.结果表明:活性炭对三醋酸甘油酯的吸附主要受到比表面积和微孔的影响,中孔对其吸附性能没有太明显的作用;中孔结构对苯、甲苯、丙酮的吸附可以起到明显的通道效应,大大提高了活性炭对挥发性有机物的去除能力.

| Abstract: | Toxic compounds of cigarette smoke had induced series health risk and air pollution. The mesoporous activated carbon from granular microporous activated carbon was prepared by Ca(NO3)2 impregnated steam activation. The micropore size and surface area of adsorbent played a major role triacetion adsorption, rather than mesopores size and volume of adsorbent. Mesopore size and volume of adsorbent increased removal rate of benzene, toluene and acetone by transport pores for the adsorption. |

| Keywords: | activated carbon mesoporous triacetin volatile organic compounds(VOCs) |
