Carbonaceous materials are a highly appealing class of adsorbents, owing to their exceptional properties, such as high surface area and thermal chemical stability. These have found successful applications in water purification. Sweet chestnut (Castanea sativa) cupules disposed waste. Valorization these residues is step forward terms circular economy sustainability. Meanwhile, per- poly-fluoroal...

Abstract The development of sustainable adsorbent materials for removing pollutants from water is great interest environmental remediation and human safety. This work presents the beneficial use cassava rhizome (CR) to produce economical efficient carbonaceous adsorbents dye removal. CR derived activated carbons (AC) magnetic AC were fabricated by one-pot hydrothermal carbonization in presence ...

Adsorption of sulfur dioxide on carbonaceous materials has been extensively studied (1-18). Activated carbon and activated carbon fibers have been found to be efficient adsorbents for the low temperature removal of SO2. It is believed that sulfur dioxide is adsorbed with two adsorption energies on activated carbons (3-12). The low energy, about 50 kJ/mol, corresponds to weak physical adsorption...

Currently used textile dyes are not highly toxic or carcinogenic, but the intense and persistent color of effluent is problematic. Of remediation processes investigated, adsorption process attractive, carbonaceous adsorbents (CAs) ideal for that purpose because their very high dye-binding capacity (DBC). In this review, potential biomass-based feedstocks to produce CAs application produced remo...

Competitive adsorption isotherms of Cu(II), Pb(II), and Cd(II) were examined on a magnetic graphene oxide (GO), multiwalled carbon nanotubes (MWCNTs), and powered activated carbon (PAC). A series of analyses confirmed the successful synthesis of the magnetic GO based on a simple ultrasonification method. Irrespective of the adsorbents, the adsorption was highly dependent on pH, and the adsorpti...

The utilisation of solid adsorbents for the selective removal CO2 from major emission points is an attractive method post-combustion carbon capture due to inherent potential retrofit and cost-effectiveness. Although focus in scientific community often centred on extremely novel, high-performance costly material development, exploitation carbonaceous another avenue research proving be promising....
