“…These characteristics enable efficient adsorption of smaller organic compounds, demonstrating that the adsorbent derived from biomass waste exhibits greater selectivity in eliminating ibuprofen. Terzyk et al [24,25] found that modifying the surface with H 2 SO 4 led to higher efficiency in drug removal compared to using HNO 3 and NH 3 . Macías-García et al [26] conducted research to examine the effects of varying concentrations of H 3 PO 4 (30-85%) on the chemical modification and adsorption capacity of AC that was prepared from kenaf.…”

This study focuses on the preparation and characterization of activated carbon derived from Argan paste cake through carbonization at 300 °C followed by activation at 800 °C, utilizing KOH as the activation agent with a ratio of 1:1. The objective of this research is to compare the adsorption capacity of the obtained sample, referred to as APC-300-800, with a commercially available granular activated carbon (GAC) purchased from Aquasorb. The preparation involved various characterization techniques such as BET (Brunauer–Emmett–Teller) analysis, XRD (X-ray diffraction), and SEM (scanning electron microscopy). BET analysis revealed that APC-300-800 exhibited a high surface area of 1937 m2/g. Subsequently, adsorption tests were conducted, leading to the observation that APC-300-800 conforms to the second pseudo-order kinetic model, and the adsorption of paracetamol can be accurately described by the Dubinin–Radushkevich isotherm model, exhibiting an R2 value of 0.89665. The maximum adsorption capacity of paracetamol on APC-300-800, as determined by the Langmuir model, was found to be 344.82 mg/g. Additionally, thermodynamic studies revealed that the adsorption process on APC-300-800 was primarily governed by physisorption, while for GAC, it was attributed to chemisorption. These findings highlight the potential of APC-300-800 as an efficient adsorbent for water treatment applications, showcasing its favorable adsorption characteristics compared to commercially available alternatives.
