粘胶基活性炭纤维用于低浓度SO_2常温脱除的实验研究

Study on removal of low concentration of SO_2 by cellulose-based activated carbon fiber

活性炭纤维(ACF)是一种新型功能性炭材料。应用粘胶基活性炭纤维(cellu lose-ACF)对低浓度SO2(571mg/m3)进行吸附氧化实验,通过改变活性炭纤维量、SO2浓度、氧浓度,观察cellu lose-ACF脱除低浓度SO2能力的变化规律。实验结果表明,随着活性炭纤维量、氧浓度的增加,cellu lose-ACF对低浓度SO2的脱除能力增强。在此基础上展望活性炭纤维在大气环保领域的应用前景。

Activated carbon fiber （ACF） is one kind of new functional material. Adsorption and conversion of low concentration SO2 by cellulose-ACF is experimentally studied. The concentration of SO2, O2 and the mass of cellulose-ACF, which have influence on desulfuration, are observed in this experiment. It is found that cellulose-ACF removes low concentration SO2 well. Accompanied by more mass of cellulose-ACF or higher concentration of O2 , cellulose-ACF shows better ability of removal of low concentration SO2. The using of ACF in controlling air pollution has a good prospect.
