“…The value of "n" and the Freundlich constants are compared with similar studies (Table 7) on the adsorption of DCF-Na. The correlation coefficient, R 2 , of 0.999 indicates that the Freundlich Isotherm model perfectly describes DCF-Na adsorption by BKW composite adsorbent [26]. Freundlich isotherm model gave the least Standard error, SSE and RMSE when compared to other adsorption models used in this study 5).…”

“…This is also supported by the relatively low error computation results as shown in Table 5. Other investigations have found that Freundlich model fits better the experimental data on diclofenac adsorption than the Langmuir model, utilizing gelatin carbon nanotubes [26], multi-walled carbon nanotubes [29], activated carbon from Persicum cyclamen tubers [30], and grape bagasse [31], and commercial granular activated carbon [36].…”

“…When the exponent, , of the Redlich-Peterson equation is equal to 1, the Langmuir isotherm is preferred, and when it is equal to 0, Henry's rule takes over and behavior resembles that of the Freundlich isotherm [24]. The value of the Redlich-Peterson parameter 'β' (-0.0863) indicates that the isotherms are more likely to follow the Freundlich model than the Langmuir model [26]. This is also supported by the relatively low error computation results as shown in Table 5.…”

Under batch experiment conditions, this work seeks to successfully remove Diclofenac-Na (DCF-Na) from an aqueous solution utilizing a composite sorbent made of Bentonite, Kaolinite clay, and Worm casting (BKW). This study investigated the structural modification of the H3PO4 Modified Clay by X-ray fluorescence and the effect of selected adsorption factors – DCF-Na concentration and modified BKW composite dosage. The concentration equilibrium data was used to study six isotherm models. Freundlich isotherm model better explained the adsorption of DCF-Na onto modified BKW composite with a correlation coefficient close to 1. Kinetics models were examined, and the Elovich model gave a better fit than other kinetic models studied. Mass diffusion mechanisms and thermodynamics studies were successfully carried out. The enthalpy change values evaluated were negative, which revealed the spontaneity of DCF-Na remediation onto modified BKW, and that DCF-Na adsorption is exothermic and occurred through a physisorption process.

“…Adsorption is a well-established process and its efficiency, simplicity, and cost-effectiveness for the removal of several types of contaminants is well-documented (Abdel Ghafar et al, 2020;Ghafar et al, 2020;Nour et al, 2021;Radwan, Abdel-Aty, et al, 2020;Radwan, El-Naggar, et al, 2021;Varsha et al, 2022). Recently adsorption attracted the researchers' attention as a potential treatment process for ECs (Chang et al, 2022;Tang et al, 2022). Figure S3a Several mechanisms such as pore-filling or partition diffusion, electrostatic interaction, hydrophobic interaction, ion exchange, Hbonding, and π-π interactions can be involved in the adsorption of ECs (Nayyar et al, 2022).…”

In the recent years a group of contaminants, known collectively as emerging contaminants (ECs), have attracted considerable attention due to their widespread in the environment, and lack of knowledge on their impacts on ecosystem and human health. This review gives an overview on the sources, impacts, and conventional treatment technologies of ECs and an in‐depth review of the literature on the state‐of‐the‐art treatment technologies and their performance in the removal of ECs from water sources and drinking water. A careful statistical analysis of the number of publications on the different treatment technologies of ECs was performed to identify the hot spots in this research area. Conventional treatment technologies are not able to remove ECs sufficiently. The discharge of raw or partially treated wastewater is the main source of ECs in the environment. The research in recent years is focusing on using advanced treatment process (AOPs), followed by adsorption and membrane technologies. From a technical point of view, AOPs surpass other treatment technologies as they can completely eradicate ECs without the generation of side products. Developing efficient, green, and cost‐effective materials to be used as adsorbents, photocatalysts, membranes, or membrane fillers, is one of the main research trends nowadays. Combined AOPs based on exploiting solar light, ultrasound and electrochemistry are gaining growing interest and show high potential for the treatment of ECs.

The presence of pharmaceuticals in ecosystems is a major health issue, calling for advanced methods to clean wastewater before effluents reach rivers. Here, we review advanced adsorption methods to remove ibuprofen, with a focus on ibuprofen occurrence and toxicity, adsorbents, kinetics, and adsorption isotherms. Adsorbents include carbon- and silica-based materials, metal–organic frameworks, clays, polymers, and bioadsorbents. Carbon-based adsorbents allow the highest adsorption of ibuprofen, from 10.8 to 408 mg/g for activated carbon and 2.5–1033 mg/g for biochar. Metal–organic frameworks appear promising due to their high surface areas and tunable properties and morphology. 95% of published reports reveal that adsorption kinetics follow the pseudo-second-order model, indicating that the adsorption is predominantly governed by chemical adsorption. 70% of published reports disclose that the Langmuir model describes the adsorption isotherm, suggesting that adsorption involves monolayer adsorption.
