“…In recent studies involving BPS adsorption on activated carbons in ultrapure water matrices, the experimental data have appropriately fit the pseudo-second-order kinetic model as shown in Table 6 [ 23 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. Nevertheless, none of the studies obtained better experimental data fits with the pseudo-first-order kinetic model.…”

“…Since this kinetic model assumes that chemisorption predominates in the process [33], the surface interactions between the adsorbate and adsorbent likely involve electron sharing or exchange. In recent studies involving BPS adsorption on activated carbons in ultrapure water matrices, the experimental data have appropriately fit the pseudo-second-order kinetic model as shown in Table 6 [23,[34][35][36][37][38][39][40][41].

This study assessed three powdered activated carbons (BETM, COCO, and SIAL) commercialized in Brazil at the bench scale in agitated reactors, analyzing their kinetic behavior and adsorptive capacity for BPS and BPA in ultrapure water. BETM exhibited the highest adsorption capacities (Q0max) for BPS and BPA at 260.62 and 264.64 mg/g, respectively, followed by SIAL, with a Q0max of 248.25 mg/g for BPS and for 231.20 mg/g BPA, and COCO, with a Q0max of 136.51 mg/g for BPS and 150.03 mg/g for BPA. The Langmuir isotherm model can describe the processes well. A pseudo-second-order model can describe the adsorption kinetics, and SIAL carbon had the highest rate constants (7.45 × 10−3 mg/g/min for BPS and 2.84 × 10−3 mg/g/min for BPA). The Weber–Morris intraparticle diffusion model suggests intraparticle diffusion as the rate-limiting step of all adsorption processes. Boyd’s model confirmed more than the mechanism actuating in the bisphenol adsorption. The results suggest that adsorbents with basic surfaces, high specific surface areas, and high mesopore volumes tend to remove BPS and BPA efficiently. Therefore, activated carbons can effectively complement the existing treatment in Brazilian water treatment plants (WTPs).

“…In addition, π-π interaction between BPS and the FRAC also occurred to a certain extent. When the pH .7, the adsorption capacity declined sharply from 0.9355 mmol/g to 0.1845 mmol/g, which was mainly ascribed to the hydrogen bonds decreased with the deprotonation of the BPS (Couto et al 2020). Besides, the electrostatic repulsion between the BPS À and negatively charged FRAC was gradually increased with an increase of pH (Goyal et al 2016).…”

Furfural residue (FR), a solid waste, was applied as the precursor to prepare activated carbon by steam activation. The Box-Behnken design (BBD) approach-based response surface methodology (RSM) was utilized to optimize the preparation conditions to evaluate their effects on the performance of activated carbon from furfural residue (FRAC). The optimum preparation conditions of FRAC were found as follows: activation temperature of 922 °C, activation time of 62 min, and the mass ratio of char to H2O of 1:4.5, resulting in 1,501.84 mg/g of iodine adsorption capacity and 1,662.41 m2/g of specific surface area. The FRAC was characterized and then the adsorption performance of BPS on FRAC was investigated. Langmuir and Koble-Corrigan isotherm models were well fitted to the experimental data, and the adsorption kinetics process was perfectly described by the pseudo-second-order model. Thermodynamic parameters showed that the adsorption of BPS was a spontaneous exothermic process. Besides, the regeneration efficiency of FRAC was over 97% after five consecutive cycles. The maximum monolayer adsorption capacity of FRAC for BPS was 3.2848 mmol/g at 298 K, indicating that the FRAC was an excellent adsorbent for the removal of BPS from aqueous solutions.

“…BPA has been classified as a priority contaminant due to its potential to elicit cardiovascular disorders and disrupt endocrine systems in both human beings and animals, owing to its estrogenic attributes (Deceuninck et al, 2019; Jiang et al, 2018). Various technologies, such as adsorption, membrane filtration, and electrochemical/photochemical methods have been developed to remove this contaminant (Berhane et al, 2016; Chu et al, 2021; Couto et al, 2020). Amidst these technologies, adsorption is commonly utilized as a straightforward and reliable method to segregate and reclaim BPA.…”

The utilization of natural clay minerals for the adsorption of endocrine‐disrupting chemicals (EDCs) presents a cost‐effective and environmentally friendly approach. However, the hydrophilic nature of clay minerals' surface limits their efficacy in removing these hydrophobic pollutants. To overcome these limitations, this study employed two cationic surfactants, cetylpyridinium chloride (CPC) and cetyltrimethylammonium chloride (CTAC), to modify kaolin minerals to enhance their capacity to adsorb a specific type of EDCs, bisphenol A (BPA), and its analogs. The experimental results validated that the surfactant‐modified kaolin exhibited remarkable efficiency in removing BPA from water. The equilibrium adsorption capacities of CPC‐K and CTAC‐K for BPA were determined to be 11.4 mg/g (pH = 2.0–8.0) and 13.4 mg/g (pH = 2.0–6.5), respectively. Kinetic analysis revealed that the BPA adsorption followed a pseudo‐second‐order kinetic process, while isotherm analysis suggested that the BPA adsorption was better described by the Freundlich model (R2 = 0.993–0.998). The surfactant‐modified kaolin demonstrated a retention of over 70% of its initial adsorption capacity after five cycles of desorption and regeneration, further confirming its potential for recycling. Additionally, these modified adsorbents exhibited excellent compatibility in removing bisphenol analogs. These findings provide valuable insights into the practical application of surfactant‐modified clay minerals for the elimination of hydrophobic organic pollutants from water.
