“…In this study, the ash content was about 4.7% of the material, and the calculated yield was close to 28%, confirming that most of the residual biomass, about 70%, was converted during the pyrolysis step. This yield is consistent with other studies that carbonized different biomasses with ZnCl 2 in proportions of 1:1 [5,16,[33][34][35]. To analyze the material surface before (Figure 1A,B) and after carbonization with ZnCl 2 (Figure 1C,D), scanning electron microscopy (SEM) was performed.…”

Brazil’s production and consumption of açai pulp (Euterpe oleracea) occur on a large scale. Most of the fruit is formed by the pit, which generates countless tons of residual biomass. A new purpose for this biomass, making its consumption highly sustainable, was presented in this study, where activated carbon (AC) was produced with zinc chloride for later use as an adsorbent. AC carbon formed by carbon and with a yield of 28 % was satisfactorily used as an adsorbent in removing the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). Removal efficiency was due to the highly porous surface (Vp = 0.467 cm3 g−1; Dp = 1.126 nm) and good surface área (SBET = 920.56 m2 g−1). The equilibrium data fit the Sips heterogeneous and homogeneous surface model better. It was observed that the increase in temperature favored adsorption, reaching a maximum experimental capacity of 218 mg g−1 at 328 K. The thermodynamic behavior indicated a spontaneous, favorable, and endothermic behavior. The magnitude of the enthalpy of adsorption was in agreement with the physical adsorption. Regardless of the herbicide concentration, the adsorbent displayed fast kinetics, reaching equilibrium within 120 min. The linear driving force (LDF) model provided a strong statistical match to the kinetic curves. AC with zinc chloride (ZnCl2), created from leftover açai biomass, is a potential alternative as an adsorbent for treating effluents containing 2,4-D.

“…The first minutes of the adsorption kinetics is attributed to the external mass transfer. This behavior has already been reported in other studies when also applying activated carbon derived from plant residues (Georgin et al 2022). It is noteworthy, that the increase in the equilibrium time with the initial concentration indicates that the surface diffusion mechanism tends to increase with the initial concentration.…”

In this study, the residual pods of the forest species Erythrina speciosa were carbonized with ZnCl 2 to obtain porous activated carbon and investigated for the adsorptive removal of the drug paracetamol (PCM) from water. The PCM adsorption onto activated carbon is favored at acidic solution pH. The isothermal studies confirmed that increasing the temperature from 298 to 328 K decreased the adsorption capacity from 65 mg g −1 to 50.4 mg g −1 (C 0 = 175 mg L −1 ). The Freundlich model showed a better fit of the equilibrium isotherms. Thermodynamic studies confirmed the exothermic nature (ΔH 0 = −39.1066 kJ mol −1 ). Kinetic data indicates that the external mass transfer occurs in the first minutes followed by the surface diffusion, considering that the linear driving force model described the experimental data. The application of the material in the treatment of a simulated effluent with natural conditions was promising, presenting a removal of 76.45%. Therefore, it can be concluded that the application of residual pods of the forest species Erythrina speciosa carbonized with ZnCl 2 is highly efficient in the removal of the drug paracetamol and also in mixtures containing other pharmaceutical substances.

[26,[175][176][177][178][179] In chemical activation, the biomass precursor is mixed with a certain amount of activator followed by heat treatment (400 to 1000 °C) of the impregnated precursor material in an inert atmosphere.

With the development of economy and increasing environmental awareness, how to effectively remove organic pollutants in wastewater is a research hotspot. Adsorption is one of the effective methods, and the adsorption material is the key factor to determine the efficiency. In this review, biomass‐derived carbon materials as adsorbents of organic pollutants and the adsorption mechanism are discussed in depth. The effects of carbonization and activation on the morphology and structure of carbon materials; the modification strategies of carbon adsorbents, the adsorption performance of biomass‐derived carbon materials for organic pollutants are described and illustrated; the future work of the biomass‐derived carbon materials is proposed.
