A novel magnetically separable composite photocatalyst: Titania-coated magnetic activated carbon

Separation and Purification Technology, 2008
Abstract A novel magnetically separable composite photocatalyst, titania-coated γ-Fe2O3 magnetic activated carbon, was prepared by depositing of anatase titania onto the surface of magnetic activated carbon (MAC) which was prepared by a simple route: directly adsorbing of magnetic γ-Fe2O3 nanoparticles onto activated carbon (AC). The prepared samples

Enhancement of biogranules development using magnetized powder activated carbon

Biodegradation, 2023
Biogranulation has emerged as a viable alternative biological wastewater treatment approach because of its strong biodegradability potential, toxicity tolerance, and biomass retention features. However, this process requires a long duration for biogranules formation to occur.

Enhanced adsorption of NO onto activated carbon by gas pre-magnetization

Science of The Total Environment, 2022
The NO removal efficiency was relatively low in the traditional activated carbon adsorption process. In this work, a gas pre-magnetization and activated carbon adsorption process was developed to enhance the adsorption of NO onto activated carbon. In this innovative and green process, the mixed gas was magnetized in the external magnetic field and then

Magnetic nitrogen-doped activated carbon improved biohydrogen production

Environmental Science and Pollution Research, 2023
Low biological hydrogen (bioH2) production due to non-optimal metabolic pathways occurs frequently. In this work, magnetic nitrogen-doped activated carbon (MNAC) was prepared and added into the inoculated sludge with glucose as substrate to enhance hydrogen (H2) yield by mesophilic dark fermentation (DF).

Preparation of magnetic activated carbon

Journal of Forestry Research, 1997
Based on the special molecular structure of surfactant, paramagnetic material used as magnetic nucleus was coated with two layers of surfactant including an inner layer and an outer layer. Magnetic reagent can combine with activated carbon due to adsorption of hydrophilic raclical of the outer surfactant layer. So activated carbon has magnetism.

Research on Magnetic activated carbon by XPS

Journal of Forestry Research, 1998
XPS(X-ray photoelectron spectroscopy) spectrometer EscA-750 was used to analyse the surface character of activated carbon, magnetic reagent and magnetic activated carbon. The distribution and change of C valence of them were determined. The conclusion is that the magnetic reagent could be adsorbed on the surface of activated carbon chemically.

Effect of magnetization on the adsorptive removal of an emerging contaminant ciprofloxacin by magnetic acid activated carbon

Environmental Research, 2022
Magnetic acid activated carbons (MAAC) were prepared from the shells of Sterculia villosa Roxb by activating the biomass and magnetizing it using the co-precipitation technique. Characterization of MAAC prior and post adsorption was performed using various microscopic and spectroscopic analytical techniques, and they verified the formation of magnetic ...

Magnetic properties of activated carbon fibers

Synthetic Metals, 1993
Abstract Magnetic susceptibilities and ESR spectra were measured for pitch-based activated carbon fibers (ACF) having huge specific surface areas (≈3000m2/g). These fibers consist of ca. 10A micro-pores with which dangling bond spins are associated. Under an atmospheric condition, a broad weakly temperature dependent ESR signal (ΔH≈800G) was observed,

Magnetic separation of magnetic activated carbons for water treatment and reuse

COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering, 2013
Purpose – The aim of this paper is the study of the magnetic separation of pollutants from water by means of a magnetic filter. A magnetic activated carbons nanometric powder that combines the well-known pollutants absorbent capacity of activated carbons with the magnetic properties of magnetite (Fe3O4) is used.
