| 摘 要： | 通过静态吸附实验和动态吸附实验,研究了pH值、电解质(NaCl)、活性炭纤维用量等因素对用棉花秸秆制备的活性炭纤维吸附水中3,4-二氯苯胺的影响,同时从动力学和热力学角度考察了活性炭纤维对3,4-二氧苯胺的吸附行为.结果表明,棉花秸秆制备的活性炭纤维可以有效地吸附3,4-二氯苯胺,电解质(NaCl)的存在对吸附有抑制作用;准二级动力学模型能够很好地描述3,4-二氯苯胺在活性炭纤维上的吸附行为;吸附等温线符合Langmuir方程,吸附行为是一个自发放热的物理吸附过程.

| Abstract: | The effect of activated carbon fiber prepared from cotton straw(CS-ACF)on the sorption behavior of aqueous 3,4-dichloroaniline was studied.The kinetics,thermodynamics,and the main factors affecting adsorption,such as pH,NaCl and activated carbon fiber dose were also investigated.The results indicated that the activated carbon fiber could effectively adsorb 3,4-dichloroaniline,and that NaCl inhibited the adsorption.The adsorption of 3,4-dichloroaniline by activated carbon fiber followed the pseudo second-ord... |
