摘要
为了探索提高聚丙烯腈（ＰＡＮ）活性碳纤维（ＡＣＦ－ＰＡＮ）对ＳＯ２的吸附性能，采用加入不同的活性组分对自制的ＡＣＦ－ＰＡＮ进行改性；研究了ＡＣＦ－ＰＡＮ和经过不同改性后的ＡＣＦ－ＰＡＮ对ＳＯ２的吸附性能。取得改性后活性碳纤维为改性前平衡吸附量的２倍以上；为活性炭的１０倍左右（ＡＣＦ－ＰＡＮ６２．９ｍｇ／ｇＡＣＦ，ＡＣＦ－ＰＡＮ（Ⅱ）（１－４）型１１３．６－１４３．７ｍｇ／ｇＡＣＦ，活性炭１４．９ｍｇ／ｇＡＣ）和吸附速率大于改性前的ＡＣＦ－ＰＡＮ的结果，由于改性大大提高了对ＳＯ２的吸附能力。
Polyacrylonitrile-based activated carbon fiber (ACF-PAN) made by the authors in laboratory was modified by adding different active components in order to improve its performance for adsorbing SO_2.Then ACF-PAN and the differently modified ACFPANs were studied on their performances for SO_2adsorption. It was found that the modified ACFPANs had an equilibrium adsorption capacity which was more than 2 times that of ACF-PAN and about 10 times that of activated carbon(ACF- PAN,62. 9mg/g ACF; ACF-PAN(Ⅱ)_(1-4), 113.6-143.7mg/g ACF; AC,14. 9mg/g AC),and an adsorption rate which was more than that of ACFPAN,so that such a modification made the capacity of adsorbing SO_2 to be largely increased.
