Activated carbon fibers prepared from cellulose and polyester–derived residues and their application on removal of Pb2+ ions from aqueous solution

Understanding reactions and pore-forming mechanisms between waste cotton woven and FeCl3 during the synthesis of magnetic activated carbon

“…elaborados por (Silva et al, 2018) , Carraro et al, (2019) (Castro, 2018), todo ello hablando desde una perspectiva de ciclo de vida, lo cual se afirma si tenemos en cuenta que cerca del 5% del espacio de un relleno sanitario está ocupado por residuos textiles (Mendoza-Castillo et al, 2016).…”

The effective removal of Pb2+ by activated carbon fibers modified by l-cysteine: exploration of kinetics, thermodynamics and mechanism

“…Compared with the traditional activated carbon particles, activated carbon fibers have more suitable pore sizes, better adsorption effect and easy recycling. 17–19 Javier 20 et al measured the effect of activated carbon fibers to adsorb both Pb 2+ -phenol and Cd 2+ -phenol simultaneously, proving that the selectivity of activated carbon fibers for Pb 2+ ions was greater than Cd 2+ ions. Deng 18 et al found that a novel thiosemicarbazide-modified adsorbent exhibited a high performance towards Cd( ii ) and Pb ( ii ).…”

Study on the Pyrolysis and Adsorption Behavior of Activated Carbon Derived from Waste Polyester Textiles with Different Metal Salts

“…The experimental pHpzc values of Zn−AC, Fe−AC, Cu−AC, and AC were observed as 4.76, 5.94, 5.93, and 5.92, respectively ( Figure 7 ). This indicated that the surface of the ACs exhibited electropositivity, which may be due to the protonation of the surface when the pH value of solutions was around 2–3 [ 39 ]. By contrast, the main forms of Cr(VI) in the solutions were the negatively charged chromate ion (CrO 4 2− ) and the hydrochlorate ion (HCrO 4 − ).…”
