“…Figure 5 illustrates that the q MO experienced a rapid increase followed by a gradual ascent to a plateau as the time interval extended from 5 min to 120 min and subsequently to 360 min across various temperatures. The initial swift rise in the q MO could be attributed to the abundance of vacant adsorption sites within the composite microspheres and the high concentration of MO in the solution during the early stage of adsorption [46]. As the availability of these sites and the MO concentration began to diminish, the rate of adsorption progressively decreased [47].…”

To develop valuable applications for the invasive weed Palmer amaranth, we utilized it as a novel biochar source and explored its potential for methyl orange adsorption through the synthesis of chitosan-encapsulated Palmer amaranth biochar composite microspheres. Firstly, the prepared microspheres were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy and were demonstrated to have a surface area of 19.6 m2/g, a total pore volume of 0.0664 cm3/g and an average pore diameter of 10.6 nm. Then, the influences of pH, dosage and salt type and concentration on the adsorption efficiency were systematically investigated alongside the adsorption kinetics, isotherms, and thermodynamics. The results reveal that the highest adsorption capacity of methyl orange was obtained at pH 4.0. The adsorption process was well fitted by a pseudo-second-order kinetic model and the Langmuir isotherm model, and was spontaneous and endothermic. Through the Langmuir model, the maximal adsorption capacities of methyl orange were calculated as 495.0, 537.1 and 554.3 mg/g at 25.0, 35.0 and 45.0 °C, respectively. Subsequently, the adsorption mechanisms were elucidated by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy investigations. It is indicated that electrostatic interactions, hydrogen bonding, π–π interactions and hydrophobic interactions between methyl orange and the composite microspheres were pivotal for the adsorption process. Finally, the regeneration studies demonstrated that after five adsorption–desorption cycles, the microspheres still maintained 93.6% of their initial adsorption capacity for methyl orange. This work not only presents a promising method for mitigating methyl orange pollution but also offers a sustainable approach to managing Palmer amaranth invasion.

<p>Chromium (VI), a ubiquitous toxin, has been associated with several human cancer types as well as immunologic, cardiovascular, developmental, neurological, and endocrine disorders. The present study investigated the selective adsorption capacity and chromium (VI) removal ability of jackfruit leaf powder (JLP, Artocarpus heterophyllus Lam.) in landfill leachate collected from eastern region of southern India. The efficiency of prepared JLP in removing chromium (VI) from landfill leachate was examined using a number of variables such as adsorbent dose, pH, and reaction time by employing the batch adsorption process. The maximum chromium removal efficiency was observed by increasing the adsorbent dose, pH, and reaction time, while the optimal dose of JLP, pH, and adsorption reaction time were found to be 0.5 g/L, pH 8, and 120 min, respectively. Batch adsorption process under optimal conditions showed adsorption capacity value of 0.19 mg/g and the chromium (VI) removal efficiency of 95%. The data were examined using kinetic and equilibrium models. The experimental data and the Freundlich isotherm and pseudo-second order kinetics models were well-matched. The SEM and FT-IR of fresh and recovered JLP revealed similar surface morphology and functional characteristics, representing the active site present in the adsorbent (JLP) showing no significant change. We performed experiments on chromium (VI) recovery from the adsorbent that resulted in the higher recovery % of chromium (VI) with 0.5 M HCl (90%). The results suggest that JLP may be employed as a cost-effective bio-adsorbent for the removal of chromium (VI) from contaminated soil and water resources.</p>

BACKGROUNDCachaça (Brazilian spirit) is an alcoholic beverage of cultural and economic importance in Brazil. Its artisanal production is usually conducted in copper alembics, which results in contamination. The development of effective biosorbents from cheap matrices is an alternative to minimize both solid waste generation and copper levels in cachaça. The present work evaluates the obtention of nanocellulose‐based materials from the major residue generated during the processing of palm heart from the Brazilian peach palm, through different processing techniques. Materials were characterized by physicochemical composition and their sorbent capacities for copper removal from aqueous solutions, and a simulation was conducted to evaluate potential application in the adequacy of cachaça to meet Brazilian legislation requirements.RESULTSThe different processing methods resulted in different cellulose concentrations, with the highest concentration in the bleached material (B3, 694 g kg−1 of cellulose), and different specific surface areas (1.02–12.4 m2 g−1). Copper adsorption onto nanocellulose obtained from peach palm external sheath is fast, with a predominance of a chemisorption mechanism. Isotherms were best represented by Langmuir's model, suggesting a monolayer adsorption. Simulations indicate that B3 is a suitable material for the removal of copper from cachaça, and small amounts of biosorbent (733.5 g) are required for the reduction of copper concentrations (10 to 3 mg L−1) in 1000 L of cachaça.CONCLUSIONThis study demonstrated that the obtention of biosorbents from peach palm solid residues is promising and this nanocellulose‐based material can be used for copper removal from contaminated cachaça. © 2024 Society of Chemical Industry.
