Adsorption characteristics of activated carbon hollow fibers

Mesoporous Activated Carbon Fibers from Lignocelullosic Materials: Adsorption Studies

High surface area and highly mesoporous activated carbon fibers (ACF) were obtained by physical activation of natural precursors (vetiver roots and bagasse) with steam and chemical activation using phosphoric acid. The textural characteristics of the activated were determined by nitrogen adsorption study and mercury porosimetry and showed that interesting porosity were obtained (SBET up to 1600...

Ligand-Depended Adsorption Characteristics of Silver Nanoparticles on Activated Carbon

Surface modification and functionalization has been an important tool for scientists in order to open new frontiers in nanoscience and nanotechnology. Desired surface characteristics for the intended applications can be achieved with surface functionalization. In this work, the effect of water soluble ligands on the adsorption capabilities of silver nanoparticles onto AC which was synthesized f...

Comparison of Adsorption Characteristics for VOCs on Activated Carbon and Oxidized Activated Carbon

In this investigation, the selected activated carbon is treated in NaOH solution or gas fluid with ozone from an ozone generator. FTIR, BET specific surface area and element analysis instruments were used to identify the difference in the chemical and physical characteristics between the activated carbon and oxidized activated carbon. The system of adsorption apparatus consists of a fixed adsor...

Enhanced CO2 Adsorption on Activated Carbon Fibers Grafted with Nitrogen-Doped Carbon Nanotubes

In this paper, multiscale composites formed by grafting N-doped carbon nanotubes (CNs) on the surface of polyamide (PAN)-based activated carbon fibers (ACFs) were investigated and their adsorption performance for CO₂ was determined. The spaghetti-like and randomly oriented CNs were homogeneously grown onto ACFs. The pre-immersion of cobalt(II) ions for ACFs made the CNs grow above with a large ...
