Commercial activated carbon fiber (ACF) has been employed as particle electrodes to degrade aqueous m-cresol in 3-D electrode systems. To enhance the electrooxidation performance, three types of new ACF modification modes (anodic oxidation, cathodic reduction, and aqueous oxidation with concentrated HNO3) were introduced in this paper. These pretre...
Fe catalysts supported on activated carbon untreated and treated by HNO3 were prepared by an ultrasound-assisted incipient wetness method and characterized using N2 adsorption/desorption, scanning electron microscopic (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Desulfurization activity was evaluated at a fixed bed rea...

We examined the sorption of heavy metals and polycyclic aromatic hydrocarbons (PAHs) to surface-oxidized activated carbon (AC) and its effect on the distribution of those compounds in sediments. Created surface oxygen groups on AC enhanced the sorption of copper, which is superior in sorption competition, in the marine sediments. In case of cadmium...
The textural characterization of a series of activated carbons prepared from olive stones, by carbonization at different temperatures (400, 550, 700 and 850 °C) and thermal activation with CO2, has been investigated using N2 adsorption at −196 °C and CO2 adsorption at 0 °C. The effect of pre-oxidation of the carbonized precursor has also been studi...
