“…10 -A. A two-stage kinetic behaviour accompanies the adsorption of BPA on two activated carbons: initially, the adsorbed amount increases significantly up to 24 h, followed by a second stage with a quasi-stable removal rate for 24–30 h. In fact, the steep increase in adsorption efficiency during the initial adsorption phase induces a large number of adsorption sites available and, thus an increase in the mass transfer rate from the solution to the adsorbent surface [ 55 ]. However, a second stable phase is observed.…”

“…Among these, in environmental studies, the equations of Langmuir, Freundlich, Redlich-Peterson, Temkin and Dubinin-Radushkevich are commonly used. 50 Soil and sediment adsorption studies use the Freundlich isotherm to describe this process [Eqn (3)]. The model proposed by Freundlich was one of the first to equate the relationship between the amount of adsorbed material and the concentration of the material in the solution in a model with empirical characteristics.…”

“…Considering this, they are not part of monitoring programs, nor are they included in current environmental control regulations and legislation. [2][3][4] Drugs are considered EOCs because their molecules are biologically active. Generally, they present lipophilic characteristics, low biodegradability, and great potential for persistence or pseudopersistence in the environment.…”

BACKGROUNDThe use of antibiotics on a large scale is a common practice in poultry farming. This research investigated the adsorption of the antibiotic ciprofloxacin (CIP) in poultry litter samples to assess the potential risk to ecosystems due to the compound mobility. This residue is used directly dispersed in agricultural soils as a biofertilizer.RESULTSExperimental data were evaluated in terms of fits of isotherm models. The mobility of CIP was assessed by the distribution coefficient and the partition coefficient related to organic matter. The studied poultry litter presented a pH of 8.5±0.1, moisture content of 20.3±1.3 %, and total solids content of 79.8±1.2 %, with a high amount of both inorganic matter (57.1±1.7 %) and organic matter (42.9±1.7 %) content in its composition. The Redlich‐Petersen isotherm was the model that satisfactory described the experimental data, with higher maximum adsorption capacities at more alkaline pHs (pH 8.0 = 3015.0±118.0 μg g‐1, pH 7 = 2916.6±1152.9 μg g‐1 and pH 6 = 410.0±18.1 μg g‐1). The log Kd (pH 6 = 0.9, pH 7 = 1.2, and pH 8 = 1.4) and log Koc (pH 6 = 1.3, pH 7 = 1.7, and pH 8 = 1.8) values obtained for the sorption of ciprofloxacin at different pHs in poultry litter were considered low (log Koc <3.5).CONCLUSIONSThe analyte does not tend to adsorb in the poultry litter and might leach to other environmental compartments. The information obtained in this study reinforces the ecotoxicological concern about antibiotic residues in the environment.This article is protected by copyright. All rights reserved.

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).
