活性碳纤维(ACF)是一种多孔材料,它可以通过物理或化学的方式从液体或气体中吸附多种成分,因此被用于许多应用中,特别是污染气体的净化、有毒气体的吸收、气体的分离、空调的除臭和水的净化等,ACF还可应用于医药领域。活性碳的另一种类粒状活性碳(GAC)同样可应用于以上各领域。尽管ACF的价格很高,但ACF的使用却更为广泛,这主要是因为其蓬松度大、孔径均匀,使它的吸收量和传质系数比粒状活性碳高12~15倍。原材料性能及碳化与活化工艺影响最终ACF的微孔数量和总表面积。由聚丙烯腈(PAN)原丝制得的ACF有着独特的吸收性能和相当高的强度。 相似文献

Antimicrobial effect of silver particles on bacterial contamination of activated carbon fibers 总被引:2,自引:0,他引:2
Even though activated carbon fiber (ACF) filters have been widely used in air cleaning for the removal of hazardous gaseous pollutants, because of their extended surface area and high adsorption capacity, bacteria may breed on the ACF filters as a result of their good biocompatibility; ACF filters can themselves become a source of bioaerosols. In this study, silver particles were coated onto an ACF filter, using an electroless deposition method and their efficacy for bioaerosol removal was tested. First, various surface analyses, including scanning electron microscopy, inductively coupled plasma and X-ray diffraction were carried out to characterize the prepared ACF filters. Filtration and antimicrobial tests were then performed on the filters. The results showed that the silver-deposited ACF filters were effective for the removal of bioaerosols by inhibition of the survival of microorganisms, whereas pristine ACF filters were not. Two bacteria, Bacillus subtilis and Escherichia coli, were completely inhibited within 10 and 60 min, respectively. Electroless silver deposition did not influence the physical characteristics of ACF filters such as pressure drop and filtration efficiency. The gas adsorptive ability of the silver-deposited ACF filter, as represented by the micropore specific surface area, decreased by about 20% compared to the pristine filter because of the blockage of the ACF micropores by silver particles. Therefore, the amount of silver particles on the ACF filters needs to be optimized to avoid excessive reduction of their adsorptive characteristics and to show effective antimicrobial activity. 相似文献
