Surface Characteristics of Ozone Treated Phenolic Based Activated Carbon Fibers

摘要

The oxygen and the hydrogen of activated carbon fibers increased from 17.0 wt% and 1.9wt% to 22.4 wt% and 2.7wt% by oxidation wih ozone in liquid phase Th eamount of functional groups and total acidity coud be controlled witnh initiators of ozone decomposition reactins The total acidity fo ACF ozone treated in NaOH solution and H_2O_2 solution increased to 0.762 meq/g and 0.824 meq/g respectively wihile that of non-treated ACF was 0.631 meq/g and PAR TICULARLY THE PHENOIC GROUP INFREAED the phenolic group only was developed whtn ACF was treated in NoOH solution large amount of phenli group and some carboxylic group were developed when ACF waws treated in H_2O_2 solution.
