“…Among the most efficient techniques, adsorption stands out due to its ease of operation, simplicity of the project and, above all, to be economically viable (Achour et al, 2021;Bulca et al, 2021;Yusop et al, 2021;Paredes-Quevedo et al, 2021;Verma et al, 2019;Machrouhi et al, 2018), being, therefore, widely used to remove certain classes of contaminants from industrial effluents (Achour et al, 2021;Bulca et al, 2021;Yusop et al, 2021;Heidarinejad et al, 2020;Ugwu & Agunwamba, 2020;Alam et al, 2020;Machrouhi et al, 2018). Studies in the literature have reported several efficient materials in the removal of aqueous contaminants such as activated carbon, zeolites, clays, biomass, fungi and bacteria (Achour et al, 2021;Heidarinejad et al, 2020;Ani et al, 2020;Alkathiri et al, 2020;Machrouhi et al, 2018).…”

“…However, due to the high costs of commercial activated carbon, alternative adsorbents that guarantee the same adsorption efficiency have been studied, with emphasis on those produced from residues from agricultural and extractive activities (Achour et al, 2021;Alam et al, 2020;Alkathiri et al, 2020;Panwar and Pawar, 2020;Kannaujiya et al, 2021;Zoroufchi Benis et al, 2020;Reza et al, 2020). Several studies report the use of these materials in the synthesis of activated carbon for remediation of effluents, such as the study by Njoku et al (2014) who studied the efficiency of activated carbon obtained from rambutan husk (Nephelium lappaceum) in the adsorption of acid yellow dye 17 (Reza et al, 2020).…”

Environmental pollution has been a point of discussion in the international community and an object of investigation by research groups, which focus on the development of remediation methods. In the current study, the bunch of açaí (Euterpe oleracea) was used as a precursor for the preparation of low-cost activated carbon in order to remove the dye 17 AY 17 from the aqueous solution. The synthesis was carried out at temperatures of 500, 600 and 700 °C, for 2.0 h in a muffle furnace. The kinetic and thermodynamic mechanism of the adsorption process of the acid yellow dye 17, and the effects of pH, contact time and initial concentration were investigated. Activated carbon carbonized at 700 °C had the highest adsorption capacity, about of 99.9% of removal of the AY. The adsorption capacity of AY 17 was slightly pH dependent with a maximum value at pH 2.0. The kinetic data show that the equilibrium time was 200 min, and the adsorption capacity of activated carbon was 99.9% at 50 mg L‒1 and 67.0% at 150 mg L‒1 of adsorbate, suggesting high adsorption capacity of the material, even in the presence of high dye concentration. The adsorption process of AY 17 is described by the pseudo-second order kinetic model, and the experimental adsorption isotherms are adjusted to the Freundlich model, indicating that the adsorption of AY 17 on activated carbon occurs with the formation of multilayers. The present study shows that this low-cost material has great potential for remediation of textile effluents.

“…In a similar process, high-rank anthracites can be activated to yield ACs with surface areas of 1900–2800 m 2 g −1 [ 52 , 63 ]. The ACs produced from commercial carbon fibers are highly microporous solids but have SSA values below 2000 m 2 g −1 [ 54 , 64 ]. Well-ordered multi-wall carbon nanotubes (MWCNTs) can be transformed to mesoporous powders with surface areas of 1200–1700 m 2 g −1 via KOH activation [ 65 , 66 ].…”

This review presents a summary of the manufacturing of activated carbons (ACs) as electrode materials for electric double layer capacitors. Commonly used techniques of open and closed porosity determination (gas adsorption, immersion calorimetry, X-ray and neutrons scattering) were briefly described. AC production methods (laboratory and industrial) were detailed presented with the stress on advantages and drawbacks of each ones in the field of electrode materials of supercapacitor. We discussed all general parameters of the activation process and their influence on the production efficiency and the porous structure of ACs. We showed that porosity development of ACs is not the only factor influencing capacity properties. The role of pore size distribution, raw material origin, final carbon structure ordering, particles morphology and purity must be also taken into account. The impact of surface chemistry of AC was considered not only in the context of pseudocapacity but also other important factors, such as inter-particle conductivity, maximal operating voltage window and long-term stability.

“…In recent decades the application of carbonaceous adsorbents in environmental remediation has received great attention due to their high specific surface area, tunable pore size distribution and surface functionalities, leading to high removal efficiencies against both organic and inorganic pollutants [6][7][8]. These characteristics are achieved using activation and modification to achieve the desired properties to attract target pollutants.…”

The carbon fibre reinforced polymer (CFRP) industry has rapidly expanded over recent due to a range of benefits, including high mechanical strength and low weight. However, issues arise when the products reach their end-of-life (EoL). At present, pyrolysis is the only method for recycling CFRPs at scale. The process is still relatively new, resulting in stigma around the reapplication of recycled fibres within many industries due to the compromised mechanical stability. In order to increase the sustainability of the industry, alternative EoL pathways must be identified.Virgin carbon fibres (vCFs) have been successfully applied as adsorbents; however, there appears to be a gap in the literature when considering their recycled counterparts. In this study, chemical activation of industrial-grade recycled carbon fibres (rCFs) using NaOH has been investigated, together with vCF as proof of concept. The adsorption capacity of methylene blue (MB) was investigated to determine the degree of activation. The UV-visible spectrometry results indicated a maximum MB removal efficiency of 21.83 % and 21.80 % for activated-vCF (AvCF) and activated-rCF (ArCF), respectively; indicating that rCF are a promising precursor for applications as adsorbents in aqueous media, despite the higher levels of impurities when compared to the virgin counterpart.
