The sensitivity of a biosensor electrode was increased by introducing hydrophilic N-groups onto the surface of a polyacrylonitrile (PAN) based activated carbon fiber. The electrospun carbon fiber was activated using KOH to improve the adsorption of glucose oxidase (GOx) enzymes through pore production and the introduction of oxygen functional group...

In this study, viscose rayon-based activated fabrics were used as the electrodes of supercapacitors. First, viscose rayon knitted fabrics underwent oxidation, carbonization and activation in a semi-open high-temperature erect furnace to produce activated carbon fabrics (ACFs). They were then treated at temperatures up to 1500 °C for one hour. Elect...

The Zn (II) adsorption capacity of lignite and coconut shell-based activated carbon fiber (ACF) was evaluated as a function of initial Zn (II) concentration, temperature and contact time in batch adsorption process in this study. Adsorption uptake increased with initial Zn (II) concentration and temperature. Optimal contact time for the adsorption ...

A multi-scale web of carbon micro-nanofibers was prepared for antibacterial applications by chemical vapor deposition (CVD) using silver (Ag) and copper (Cu) bimetal nanoparticles (Nps). Carbon nanofibers (CNFs) were grown on activated carbon fiber (ACF) substrate using acetylene as the carbon source. The CVD conditions were optimized such that Cu ...

Phosphate removal from water is crucial to the prevention of eutrophication. The phosphate adsorption performance from aqueous solutions by using lanthanum-doped activated carbon fiber (ACF-La) was developed by batch and continuous column adsorption method. The batch sorption condition with respect to interfering ions was tested, and the pseudo sec...

Adsorption
In this work, the adsorption of Pb(II) from aqueous solution was investigated on various types of activated carbon fibers (ACFs) manufactured from polyacrylonitrile and phenolic resin. The textural and physicochemical properties of the ACFs were determined by the N2-BET method and acid-base titration. The experimental adsorption equilibrium data of...

A study on the electrosorption of uranium (U(VI)) ions onto a porous activated carbon fiber was performed to treat lagoon sludge containing 100 mg/L uranium and high concentration of chemical salts composed 3.8% NaNO3, 19.8% NH4NO3, 1.9% Ca(NO3)2. The applied negative potential increased the adsorption kinetics and capacity in comparison to the ope...

The surface chemistry of activated carbon fiber (ACF) was modified by CuSO4. The static adsorption capacities of modified ACF for different volatile organic compounds (VOCs) were determined. The result indicates that ACF modified by CuSO4 could get higher adsorption capacities for the vapors of benzene, toluene, methanol and ethanol than the untrea...
