Summary: This study focuses on the production of activated carbon from rubber fig leaves and its composite with iron oxide nanoparticles (RFAC@Fe2O3), as well as its ability to adsorb tetracycline. The physical and functional properties of RFAC@Fe2O3 nanocomposite were analyzed. The nanocomposite exhibited a high surface area, pore size, and mesoporous nature, making it suitable for adsorbing pollutants. The adsorption of tetracycline by RFAC@Fe2O3 was optimal at pH 4.0, and increased with higher nanocomposite dosage and stirring speed. The adsorption process followed the Freundlich isotherm and pseudo-second-order model.

Summary: The development of a magnetized activated carbon adsorbent with improved separation efficiency for the removal of antibiotics from water was studied. The adsorbent exhibited competitive adsorption properties between TC and LM, and the process was endothermic. Non-isothermal fitting of the data into different adsorption models provided insights into the adsorption behavior of the system. Redlich-Peterson isotherm accurately predicted TC adsorption data at different temperatures, while the extended Langmuir model accurately predicted the binary adsorption system.

Summary: In this study, an O-modified activated carbon fiber (O-ACF) was prepared and used for the adsorption of Cu (II) in water. The O-ACF electrode showed excellent electro-adsorption performance for Cu (II), with a maximum adsorption capacity 1.63 times higher than that of commercial activated carbon. The optimal working conditions for electro-adsorption of Cu (II) by O-ACF electrode were found to be a voltage of 1.0 V, a solution pH of about 6, and an electrode plate spacing of 10 mm. The study also demonstrated the practicality of O-ACF for Cu (II) adsorption through adsorption regeneration experiments.

Summary: In this study, a novel composite material LDH@CNT was prepared using an in-situ method, which had a favorable adsorbent structure due to the mutual support of LDHs and CNTs. The adsorption kinetics of LDHs, CNTs, and LDH@CNT composites for tetracycline were well described by intraparticle diffusion and pseudo-second-order models, indicating that the adsorption site played a major role. The Generalized Langmuir model was found to better describe the adsorption process than the Langmuir model, suggesting multiple interactions between tetracycline and the composite material. Site energy distribution theory combined with molecular simulation explained the adsorption mechanisms, and the removal of tetracycline by LDHs, CNTs, and LDH@CNT composites was calculated. The results showed that LDH@CNT composites had lower average site energies compared to LDHs and CNTs, but had more exposed adsorption active sites, leading to improved removal efficiency of tetracycline.

Summary: The removal of reactive red M-2BE dye from aqueous solution using multi-walled carbon nanotubes and powdered activated carbon was studied. Machine learning algorithms were used to model the kinetic adsorption, and the SHapley Additive exPlanations (SHAP) were employed to interpret the effect of each feature on the adsorption capacity. The results showed that the ANFIS model had the best statistical metrics, and temperature had the least contribution in describing the adsorption capacity. This novel application provides important insights for adsorption research.

Summary: This study investigated the recovery of Gd3+ from real leachate of phosphogypsum using natural bentonite clay. The adsorption study revealed that the clay has typical bentonite characteristics and can effectively adsorb Gd3+. The kinetics and thermodynamics of the adsorption process were analyzed, and it was found that the Langmuir model and Avrami fractional order model were suitable for describing the adsorption isotherms and kinetic data, respectively. The study also showed that citric acid was an efficient desorbing agent for Gd3+ from the bentonite, and the clay could selectively recover Gd3+ from the real leachate of phosphogypsum.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
