Mechanochemically improved surface properties of activated carbon cloth for the removal of As(V) from aqueous solutions

Mechanically activated carbonized rayon fibers as an electrochemical supercapacitor in aqueous solutions

“…The single-walled CNTs [23] and graphite [27], upon ball milling became capable of intercalating high amount of lithium ions. Mechanochemically treated microporous activated carbon cloth, obtained by simultaneous carbonization and CO2-activation of viscose rayon cloth [29], may be used as effective adsorber of As (V) [30] and some other pollutant ions (zinc, cadmium mercury) [31] from aqueous solutions.…”

Telas de carbón activado: generalidades y aplicaciones

“…Después de la estabilización, las fibras o los tejidos se someten a un tratamiento térmico (carbonización) a una temperatura de aproximadamente 800 °C a 1000 °C en una atmósfera inerte (Tripathi, Singh, Sathe, Thakare & Singh, 2018). Para la preparación de TCA se utilizan como precursores diversos materiales poliméricos, como nylon, rayón, celulosa, resina fenólica, poliacrilonitrilo (PAN) y brea (Matovic et al, 2016;Babic, Milonjic, Polovina, & Kaludierovic, 1999).…”

“…Debido a que han incrementado su nivel en la contaminación y presentan un riesgo para la salud humana, es necesario la investigación y el desarrollo de métodos más efectivos para su eliminación (Masson et al, 2016). En las últimas décadas, los materiales a base de carbono, como las TCA, se usan ampliamente para descontaminar el agua de materiales orgánicos e inorgánicos debido a su alta capacidad de adsorción y no toxicidad (Matovic et al, 2016;Gineys, Benoit, Cohaut, Béguin & Delpeux-Ouldriane, 2016). La capacidad de adsorción de un carbón activado depende de las propiedades de su textura, las propiedades químicas de la superficie, la naturaleza del adsorbente utilizado, así como la naturaleza y la concentración del adsorbato y el pH de la solución (Kumita et al, 2018;Blanco, Giraldo & Moreno, 2007;Babic, Milonjic, Polovina, Cupic & Kaludierovic, 2002).…”

Preparation and adsorption performance evaluation of activated carbon fibers derived from rayon

“…Recently, activated carbon fibers (ACFs) are known as carbon related materials. ACFs derived from several fiber sources have been adapted as filter materials [3,4]. ACFs exhibit strong adsorption performance, which is generally higher than that of conventional activated carbon [3][4][5].…”

“…ACFs derived from several fiber sources have been adapted as filter materials [3,4]. ACFs exhibit strong adsorption performance, which is generally higher than that of conventional activated carbon [3][4][5]. Several methods for the preparation of ACFs, such as chemical modification and heat treatment have been studied; however, the adsorption abilities of ACFs could be potentially improved by ACF preparation methods.…”
