摘要：
Two types of tailored activated carbons (BC-41-OG and BC-41-MnN) with favorable physicochemical characteristics were employed as adsorbents to study effects of synthetic small organic molecular (phenolics) on fulvic acid (FA) removal. The adsorption of FA on activated carbon was greatly declined due to competitive adsorption as a result of oxidation coupling of phenolics. However, the physicochemical characteristics of novel activated carbons (surface metal oxides and mesoporosity) can play an important role in alleviating this effect. The adsorption of FA onto F400 fluctuated a lot due to a relatively lower mesoporosity and surface basicity. Kinetic study was also conducted to determine the effects of oxidative coupling on adsorption kinetics of FA. The results demonstrated that presence of phenolics caused more significant effect on FA adsorption kinetics as compared to humic acid (HA).
