“…With an increase in Ce, the adsorption capacity also increased significantly, reaching values of approximately 5.7 g g −1 for lactose, 1150 mg O2 g −1 for BOD5, and 11,000 mg O2 g −1 for COD (experimental values). It is evident that the adsorption capacity benefitted from higher temperatures, with the highest values observed at 318 K. This phenomenon can be attributed to the thermal agitation effect, where an increase in agitation rate reduces the film resistance to mass transfer around the adsorbent particles, enhancing the adsorption of molecules present in the cheese whey onto the active sites of ACPO4 [93,94]. In summary, these results confirm that ACPO4 can effectively be employed for the treatment of cheese whey through the adsorption process.…”

Brewer’s spent grains (BSG) are a significant by-product of beer production, and its improper disposal poses environmental challenges. This study investigated the use of BSG for activated carbon production with phosphoric acid as a chemical activator and its application in cheese whey remediation through liquid-phase adsorption. The adsorbent was thoroughly characterized through using techniques such as FTIR, SEM, N2 isotherms, and surface charge distribution. The adsorbent exhibited substantial pores, a high surface area (605.1 m2 g–1), good porosity, and positive surface charges that facilitated favorable interactions with cheese whey compounds. Equilibrium was achieved in 330 min for lactose, BOD5, and COD. The maximum adsorption capacities were 12.77 g g–1 for lactose, 3940.99 mg O2 g–1 for BOD5, and 12,857.92 mg O2 g−1 for COD at 318 K. Removing these adsorbates from cheese whey effluent reduces its organic load, enabling water reuse in the manufacturing unit, depending on its intended use. The adsorption process was spontaneous and endothermic, with ΔH° ≥ 265.72 kJ mol−1. Additionally, the activated carbon produced demonstrated impressive regeneration capability with sodium hydroxide, maintaining 75% of its adsorption capacity. These results emphasize the potential of activated carbon as an effective adsorbent for cheese whey remediation, providing a sustainable solution for waste management in the dairy industry and water reuse.

This inquiry used ultrasonic waves to uptake paracetamol (PA) by using oak-based activated carbon (ACO). The surface of ACO was explored based on FT-IR, SEM, and XRD before and after the adsorption. The kinetic data for PA adsorption onto ACO corresponds to a pseudo-second-order kinetic model. Isothermal models of the Langmuir, Freundlich, D-R, and Temkin were used. The adsorption of PA onto ACO was found to be a monolayer with 96.03% uptake, which corresponds to Langmuir. The thermodynamic experiments revealed the endothermic nature of PA adsorption onto ACO. Under the investigated optimal conditions, the adsorption capacity of PA onto ACO was found to be 97.1 mg. L-1. ACO could be recycled after six regenerations. Ultimately, sonicating has adequate performance for the uptake of PA by ACO.

BACKGROUNDIn pressing environmental challenges, practical solutions to remove organic contaminants from water are paramount. This study undertook a crucial task of comparing two adsorbents: BT‐KOH, synthesized from Tingui bark activated with potassium hydroxide, and Norit commercial carbon. The comparison was based on experimental data from adsorption kinetics and isotherm tests in batch and fixed bed systems, targeting the removal of acetaminophen and diclofenac. Physico‐chemical characterization analyses of the materials were also conducted to enhance the comparison.RESULTSThe study's key finding was the superior performance of BT‐KOH over Norit in removing acetaminophen and diclofenac. The maximum adsorption capacities for acetaminophen were 357.7 mg g−1 for BT‐KOH and 226.3 mg g−1 for Norit. For diclofenac, these values were 250.6 mg g−1 for BT‐KOH and 220.9 mg g−1 for Norit. This superiority was attributed to BT‐KOH's larger specific surface area and higher quantities of oxygen‐containing functional groups.CONCLUSIONThe result underscores the importance of considering the physical–chemical composition of materials in the quest for more effective and sustainable water treatment methods. © 2024 Society of Chemical Industry (SCI).
