“…Previously, Ramli et al successfully introduced PMT to explain the mass transfer between methylene blue and jengkol peel activated carbon. However, Yusop et al [48][49][50] modified the previous PMT model by changing the predicted adsorbent surface area unit from cm 2 g −1 to m 2 g −1 . As a result, a direct comparison between the experimental and predicted surface area can be made.…”

“…Some of them include almond shells, rice husks, cherry stones, meranti woods, orange peels, olive stones, coconut husks and jengkol peels amongst others. [28][29][30][31][32][33][34][35] In addition, AC has been extensively employed in wastewater treatment due to its paramount properties, such as a porous structure, very large surface area and the ability to adsorb pollutants selectively. 36,37 For instance, Spessato et al 38 successfully achieved maximum acetaminophen adsorption capacity (Q m ) for super-activated carbon at 356.22 mg g −1 .…”

BACKGROUNDAcetaminophen, also known as paracetamol, has been notably detected in aquatic environments, including wastewater, surface water and drinking water, causing significant concern within the scientific and environmental research communities. This study focuses on two main objectives: (i) optimizing corn cob‐based activated carbon (CCAC) through response surface methodology for the adsorption of acetaminophen and (ii) simulating the acetaminophen adsorption process using the polymath mass transfer (PMT) model.RESULTSThe optimized CCAC was prepared via physiochemical activation under microwave radiation (265 W power) for 6 min, with a KOH impregnation ratio of 0.50 g g−1. This process resulted in a high Brunauer–Emmett–Teller surface area of 976.29 m2 g−1, accompanied by a corresponding pore volume of 0.39 cm3 g−1 and a pore diameter of 2.38 nm. The adsorption study, employing differential initial concentrations (ranging from 5 to 30 mg L−1) of acetaminophen, revealed a substantial adsorption capacity of 22.43 mg g−1 (74.77%) at 30 °C and 20.74 mg g−1 (69.13%) at pH 6. The PMT model indicated an adsorption capacity (Qm) of 21.14 mg g−1, with an error of 5.75%, demonstrating high precision compared to the experimental result. Additionally, the calculated R2 values equal to or above 0.90 indicated strong agreement between the PMT model and experimental data.CONCLUSIONThus, applying the PMT model proved to be economical and cost‐effective, providing accurate predictions on surface area during adsorption performance compared to the time‐consuming and costly process of conducting characterizations. © 2024 Society of Chemical Industry (SCI).
