“…Next, MB adsorption isotherms were investigated to get a better comprehension of the interaction between adsorbate molecules and the adsorbent surface. 54 Temkin, Langmuir, and Freundlich, as the most popularly used models, were studied. 55 The Langmuir isotherm model assumes the single-layer adsorption process onto an adsorbent with uniform and homogeneous adsorption sites.…”

A Fe3O4@activated carbon‐COOH (Fe3O4@CFC‐COOH) was prepared via carboxyl‐functionalization of the activated carbon derived from feather waste, followed by co‐precipitation of Fe2+ and Fe3+ under alkaline conditions. This hybrid organic–inorganic porous compound was applied for in‐situ synthesis of TMU‐16 metal–organic framework and, subsequently, further engaged as support for immobilizing of Cu nanoparticles. The multi‐application of the as‐synthesized nanocomposite was investigated in the synthesis of tetrahydrobenzo[b]pyrans derivatives and the removal of methylene blue from aqueous media. The maximum absorption percentage (Re) for the removal of methylene blue was 96%. The adsorption process fitted well with the Freundlich model and has followed the pseudo‐second‐order kinetic model. Also, the Fe3O4@CFC‐COOH@TMU‐16@Cu exhibited high catalytic activity in the synthesis of tetrahydrobenzo[b]pyran derivatives with a wide range of aldehydes bearing electron‐donating and electron‐withdrawing groups.

“…It was found that the maximum adsorption capacities of activated carbon were147.1, 151.5, and 151.5 mg/g at 303, 313, and 323 K, respectively. Tabassum et al 153 examined the samples of activated carbon obtained from betel nut husks with chemical activation using NaOH. The sample was processed with methylene blue to examine its maximum adsorption capacity.…”

Biomass can be converted into energy, fuels, and value-added products by adopting proper conversion or production methods. For many years, biomass has been considered to be a good candidate for producing biochar or activated carbon. The awareness created on mitigation of carbon dioxide (CO2), which is the major cause of global warming, necessitated developing potential methods and materials for curbing CO2 originating from various sources. Adsorption is the most viable option to mitigate CO2 by using activated carbon which can be derived from various biomass sources. In recent years, activated carbon has been produced from different biomass substances by varying carbonization and activation duration, carbonization and activation temperature, impregnation ratio, and the concentration of the activating agent to improve its surface area and porosity. This review article provides a comprehensive review on utilization, production and characterization of biomass-based activated carbon for CO2 adsorption. Initially, the article discusses the review of research works carried out on utilization of biomass-based activated carbon for CO2 adsorption. Furthermore, the article presents the research works carried out on surface textural characteristics, physicochemical properties, and maximum adsorption capacity of activated carbon obtained from different biomass substances. Finally, the article presents the research works carried out related to the biomass-based activated carbon and the parameters significantly enhancing the CO2 adsorption performance.

“…The greater the C-value, the thicker the boundary layer; hence, the rate of diffusion could not be neglected [39]. The adsorbate will be moved slowly through the boundary layers into the active sites of adsorbent if the adsorption is controlled by diffusion [40].…”

Toxicity of methylene blue (MB) in water bodies has a negative effect on environment and living organisms. The presence of MB in water could last longer in view of the non-biodegradable characteristic. In this study, hydrochar was used as adsorbent to remove MB from aqueous solution. Hydrochar derived from bagasse was successfully prepared by hydrothermal carbonization treatment at temperature of 270oC, and pressure of 10 Bar for 30 minutes. For enhancing the adsorption ability, hydrochar was activated by adding KOH that was able to increase the percent removal by ~11%. The hydrochar was characterized using FTIR before and after adsorption. The results showed that the dominant functional groups of hydrochar included O-H, C=O, -O- and aromatic compounds. Whereas, the functional group of azo groups such as N-H and N=N appeared after adsorption. The maximum adsorption capacity (Qmax) was 5.1204 mg/g, while the adsorption isotherm of MB onto hydrochar followed the Langmuir and Freundlich model. The adsorption mechanism belongs to chemical adsorption, and the rate of diffusion can be neglected because the adsorption kinetics fitted well with pseudo-second order and the value of k2 > kdif > k1. Thermodynamic studies indicated that the adsorption process is classified as endothermic and reversible at room temperature. The results showed that hydrochar could be the alternative adsorbent for removing MB in wastewater. In addition, sugarcane bagasse has a great potential as feedstock of hydrochar.
