Activated Carbon Fabric: An Adsorbent Material for Chemical Protective Clothing

Abstract

<p class="p1">Activated carbon fabric or fiber (ACF) is a novel carbonaceous material with exceptionally high adsorption rate and larger adsorption capacity, that has emerged as a rising star in the field of adsorbents. ACF has many advantages over other commercial porous storage materials such as granular activated carbon and powdered activated carbon in terms of adsorption capacity, well defined microporous structure, stability, flexibility and ease of lamination to various substrates. In the last few years, activated carbon fabrics have gained greater choice of interest for use as an adsorbent material in several fields including nuclear, biological and chemical (NBC) protection suit. Viscose rayon, acetate, polyacrylonitrile, pitch, and phenolic based materials are mainly used as precursors for preparation of ACF. ACF or fibres are generally prepared by process comprising stabilisation, carbonisation and activation of precursors. Reviews recent advances and developments in the field of ACF and their utility as an adsorbent material in various fields including NBC scenario. ACF with unmatchable pore structure and surface characteristics at present, with continued innovations and attention to its key challenges, it is expected that ACF will play a pivotal role in diverse environmental, defence<em>, </em>and civil applications.</p>

Activated Carbon Fabric Respiratory Mask reduces Blood Lead, Oxidative Stress and Improves the Antioxidant Status and Liver Functions in Unorganised Battery Workers

“…KIMSDU/IEC/03/2016, Dated 8/11/2016, Protocol No. 2016-2017) before the enrolment of study participants. And all the procedures of this study were followed as per the 1964 Helsinki declaration.…”

“…In textile, dye, and metal processing industries, where lead is used, the ACFs are mainly used for the removal of lead from waste liquids by the adsorptive process (Basso et al, 2002;Betancur et al, 2009). The other toxic metals such as cadmium, copper, nickel, chromium, and zinc were also removed by using ACFs (Thakare et al, 2017).…”

Telas de carbón activado: generalidades y aplicaciones

“…Por lo tanto, la velocidad de adsorción en las TCA es mucho más rápida que las formas tradicionales del carbón activado (Leyva Ramos, a intervalos amplios, produciendo telas permeables con una superficie lisa (Matatov-Meytal & Sheintuch, 2002). 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).…”

Chemical Protection Studies of Activated Carbon Spheres based Permeable Protective Clothing Against Sulfur Mustard, a Chemical Warfare Agent

“…Protective clothing is required to protect the wearer against a variety of chemical and biological agents 2 . Protection is required against liquid droplets, aerosol and vapour of chemical warfare agents which can penetrate dermally and are threat to the combatant 3 . Therefore, there is a requirement to develop the NBC protective clothing which can be used effectively under NBC scenario without affecting the tactility of combatant.…”
