“…Zbair et al [86] studied the adsorption of bisphenol A in water by activated carbon prepared from argan nut shells and activated by phosphoric acid, removing 1250 mg/g BPA. e optimized variables were 0.01 g, 60 mg L −1 and 6.5 as adsorbent dosage, initial BPA concentration, Montmorillonite clay modified with Lmethionine amino acid was used for amoxicillin adsorption [100] and pH. Adsorption experiments revealed that the adsorbent was more efficient due its large specific surface area (1372 m 2 /g).…”

The rapid growth of anthropogenic activities in recent decades has resulted in the appearance of numerous new chemical compounds in the environment, known as “emerging pollutants” (EPs) or “contaminants of emerging concern” (CECs). Although partially or not yet regulated or monitored, there is growing research interest in these EPs among the scientific community because of their bioaccumulation, persistence, and adverse effects. Among these, endocrine disruptors, pesticides, and pharmaceuticals can have harmful impacts on human health and the ecosystem. Conventional wastewater treatment technologies are not effective in removing these contaminants, allowing them to be released into the receiving environment. In order to improve the understanding of emerging pollutants, this review discusses the source, occurrence, and impacts of bisphenol A, atrazine, amoxicillin, and paracetamol as model molecules of emerging environmental pollutants, an issue that remains underrepresented in Morocco. Then, treatment methods for EPs are reviewed, including adsorption, advanced oxidation processes, biodegradation, and hybrid treatment. It is proposed that adsorption and photocatalysis can be used as simple, effective, and environmentally friendly technologies for their removal. Thus, we summarize some of the adsorbent and photocatalyst materials applied in recent work to control these pollutants. Towards the end of this paper, the development of inexpensive and locally available (Morocco) materials to remove these compounds from wastewater is considered.

“…(1) A weight loss in the range 100-150 • C present in all the samples, but larger and more complex in pristine ADS, which is related to the release of water molecules allocated inside the clay interlayer and/or in the zeolite cages. Water evolution is lower in the case of the ADS 3C and 6C samples, as water molecules displacement occurred upon methionine intercalation [16]. Water evolution in the mechanical mixture is only barely evident due to the strong methionine decomposition.…”

“…Moreover, the use of montmorillonite, modified with protonated L-methionine via a cation exchange process, has been proposed for fast and efficient adsorption of amoxicillin from aqueous solutions. The improved clay spacing has been reported to facilitate the amoxicillin adsorption process, and an enhanced adsorption capacity has been reported for the modified montmorillonite, compared to the pristine clay [16].…”

Natural Clays as Potential Amino Acids Carriers for Animal Nutrition Application

This study has the main purpose of testing natural carriers as more sustainable alternatives to polymeric coating. New clay-based hybrid organic–inorganic materials have been prepared. An innovative procedure for the intercalation of the bioactive molecule is proposed. The synthesis process implies the use of mild operating conditions and does not require the use of organic reactants or solvents. Moreover, the use of natural carriers, and milder environmentally friendly process conditions, fulfill the requirement of a mostly safe, greener production. The capture and the release properties of the final material mainly depend on the carrier morphology. Large zeolite content in the mineral clays can favor the capture of very large methionine loadings, but due to the trapping mechanism, typical of these structures, zeolites prevent a satisfactory release in mild condition and physiological condition. The Freundlich adsorption model has been found to be able to predict the capture behavior. Once the proper carrier is selected, the preparation procedure guarantees the protection of the amino acid in the right form. Neither the structure of the inorganic matrix nor the amino acid structure was changed in the preparation process. Methionine was detected in its zwitterionic form, showing the main IR bands only slightly affected by the interaction. Further studies on methionine bioaccessibility and intestinal absorption from methionine–Adsorbene (MET–ADS) are required to optimize the application of natural clay in in-field animal nutrition.

“…For both materials the values of ΔH and ΔS are negative, which indicates an increase in the randomness in the liquid-solid interface (adsorbent) during the adsorption process and an exothermic nature of the sorption process, in addition there is a strong interaction between the sorbent and the chemical species of the compounds [74]. The increase in temperature in the system decreases the binding potential at equilibrium, therefore, the adsorption capacity also decreases [75], both for C-Fe/Ce and for CB.…”

This research presents the obtaining of a biochar (CB) from the use of pomegranate peel (Punica granatum) conditioned with iron and cerium nanoparticles (C-Fe/Ce), as well as its characterization by SEM (Scanning Electronic Microscopy), FTIR (Fourier Transform Infrared Spectrometry), TGA (Thermogravimetric analysis), EDS (Energy Dispersive Spectroscopy), XPS (X-Ray Photoelectron Spectroscopy) and evaluation of the adsorption capacity of ampicillin (AMP) in aqueous phase at 20, 30 and 40 C. The maximum adsorption capacity for CB was 18.97 mg g À1 and for C-Fe/Ce, 27.61 mg g À1 at pH of 7, observing that with increasing temperature, the sorption capacity decreases in both materials, the experimental data was fitted to various mathematical models and the best fit was the pseudo-second order model for the kinetics, whilst for the adsorption isotherms the best fit was with the Langmuir model, indicating that the adsorption process is carried out in a monolayer on a homogeneous surface, through a chemisorption process. According to the thermodynamic parameters this process is carried out through an exothermic reaction. The results obtained indicate that both materials are suitable for the removal of AMP in the aqueous phase and that they can be reused up to 5 times.
