“…A The isotherm obtained presents a characteristic profile of the type IV isotherm, according to the classification of the International Union of Pure and Applied Chemistry (IUPAC), (Foo and Hameed, 2012;Sing, 1982) with an H4-type hysteresis cycle in the P/P0 range from 0.4 to 0.99 , suggesting that the surface of CA-CA700 is predominantly constituted by mesopores (Munagapati et al, 2021;Sing, 1982;Shoaib et al, 2020;Hamza et al, 2018). The textural properties obtained by the BET and BJH methods, indicate that the material has a surface area of 353 m 2 g -1 , average pore diameter of 3.628 nm and pore volume of 0.046 cm 3 g -1 corroborating the presence of mesopores in the structure, since for this type of isotherm the diameter range for mesoporous material is between 2.0 and 50 nm.…”

“…The contamination and degradation of the environment by polluting gases, residues from agricultural activities, organic waste, toxic chemical products and other polluting sources has been the subject of debate in today's society (Chen et al, 2020;Khattab et al, 2020;Kishor et al, 2021;Nambela et al, 2020;Sarkar et al, 2017;Ignachewski et al, 2010). These pollutants promote an imbalance in the environment, and have reduced drastically the quality of available drinking water (Kishor et al, 2021;Munagapati et al, 2021;Hynes et al, 2020;Berradi et al, 2019;Sarkar et al, 2017;Ignachewski et al, 2010).

“…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). Other works address the removal of acid yellow dye 17 using activated carbon obtained from eggplant residues, achieving maximum removal of 99.58 % (Kannaujiya et al, 2021), and the removal of anionic acid yellow dye 17 using avocado seed powder, showing excellent removal over a wide pH (Munagapati et al, 2021), range and adsorption study of acid yellow dye 17 using activated carbon obtained from the rice husks, providing a maximum removal of 99.98% (Patil et al, 2015). However, most of these works use synthesis routes with inert gases, such as nitrogen and argon, which increase the cost of the process (Reza et al, 2020;.Patil et al, 2015).…”

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.

The removal efficiency of an anionic acid dye, Acid Orange 10 dye (AO-10), and hexavalent chromium metal Cr(VI) from an aqueous medium using carboxymethyl xanthan gum-g-poly(4-vinyl pyridine), CMX-g-P(4VP), as a novel adsorbent was studied. The influences of pH, adsorbent dose, temperature, and equilibrium time on the adsorption process were evaluated to optimize the conditions for maximum removal of the adsorbate. Both AO-10 and Cr(VI) removal were pH-dependent, with the most excellent adsorption capacity occurring at pH 2.5. AO-10 and Cr(VI) had maximum adsorption capacities of 1961 and 492 mg g À1 , respectively, considerably high. The adsorbent may be efficiently reused for five cycles, according to the desorption studies. The experimental adsorption equilibrium data were described using the Langmuir, Freundlich and Dubinin-Radushkevich isotherm models. The Langmuir is judged the closest to the description of the practical. In addition, the kinetics of the adsorption process is controlled using pseudo-first-order and intraparticle diffusion kinetic models, while the thermodynamic process proved the spontaneous and exothermic nature of removing AO-10 and Cr(VI) ions. Overall, the results showed that CMX-g-P(4VP) might be a very efficient re-usable adsorbent in wastewater treatment.

Adsorbents from local materials with high adsorption capacity (Qm) are strongly needed. In this study, mandarin peels (MP) as a local waste material were refluxed in 80% sulfuric acid (H2SO4) to produce a novel biochar, which was oxidized by boiling in 50% hydrogen perioxide (H2O2) and then aminated via refluxing in tetraacetic acid (TETA) to produce mandarin biochar‐C‐TETA (MBCT). Fourier transform infrared (FTIR), Brunauer–Emmett–Teller (BET), Barrett–Joyner–Halenda (BJH), scanning electron microscopy (SEM), energy‐dispersive X‐ray (EDX), X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS) and thermgravimetric analysis (TGA) studied various characterizations of MBCT. The optimal pH for AY17 dye absorption was discovered to be 1.5 using 0.75 g L−1 MBCT, the maximum absorption capacity predicted for the MBCT was 1250 mg g−1. The high new absorption peaks at 1439.89 and 1362.38 cm−1 in MBCT imply that amino groups were successfully generated onto the surface of MBCT due to TETA treatment. The experimental data were examined using the Langmuir (LNR) and Freundlich (FRH) isotherm models. The FRH best explained the experimental MBCT data. The pseudo‐first‐order (PFOM) and pseudo‐second‐order (PSOM) models, intraparticle diffusion (INDM) and film diffusion (FDM) models were applied to calculate the kinetic data. The PFOM rate model ideally defined the absorption of AY17 dye to MBCT with a linear regression coefficient (R2 > 0.99). The key mechanism for absorbing AY17 dye molecules to MBCT was chemisorption, which entails the distribution or exchange of electrons between the absorbent and the dye due to the valency force. According to the findings, the novel MBCT adsorbent had a remarkable adsorption capacity (Qm = 1250 mg g−1) and could be reused without losing its absorption effectiveness. © 2023 Society of Chemical Industry (SCI).
