Summary: A Moroccan clay enriched with silica and alumina was used to adsorb phenol from aqueous solutions. Various characterization techniques were employed to examine the physical and chemical properties of the clay. The adsorption kinetics were rapid and followed the pseudo-second-order model, with an impressive adsorption capacity near 97 mg/g. Investigation into the interaction mechanism between phenol and clay revealed the nucleophilic sites in phenol engaging with the positive sites of the silica and alumina phases. The clay also showed potential for reuse in pottery production without significant alterations in flexural strength.

Summary: Waste pea shells were utilized to synthesize an efficient adsorbent (USAPS) for phenol removal, with the use of ultrasound during the chemical activation enhancing adsorption properties. Factors such as pH, temperature, USAPS dose, phenol concentration, and inorganic salt addition were studied to understand phenol adsorption behavior. The kinetic and equilibrium data were best fitted with the pseudo-second-order kinetic and Langmuir models, respectively, indicating a physical adsorption process with no structural alteration at the adsorbent-adsorbate interface.

Summary: This study investigated the feasibility of using raw date palm fiber (RDPF) and NaOH chemically modified date palm fiber (NaOH-CMDPF) obtained from discarded agricultural waste for removing phenol in water. The adsorbent was characterized using different techniques, and it was found that NaOH modification increased phenol adsorption capacity. The results showed that NaOH-CMDPF had a higher removal rate (86%) compared to RDPF (81%). Both RDPF and NaOH-CMDPF had high adsorption capacities and followed the pseudo-second-order kinetic process.

Summary: In this study, Zeolite (ZSM-12) materials were obtained from residual alum sludge of drinking water treatment plants. Calcination at different temperatures (400°C, 600°C, and 800°C) resulted in the formation of AS400, AS600, and AS800 materials. The AS400 material showed the highest adsorption capacity for phenol and can be used for environmental remediation.

Summary: Collagen-(AMPS-MAA/AAm)-Fe3O4@SiO2 magnetic double-network nanocomposite hydrogel (DNNH) was successfully synthesized through in-situ free-radical copolymerization. The DNNH showed superior mechanical properties compared to the pure double network hydrogels (PDNH). The adsorption capacity of DNNH for phenol and 4-nitrophenol was found to be strong, with the hydrogel being reusable for successive 4 times.

Summary: This study successfully synthesized alumina-zirconia composite and evaluated its performance in the removal of phenol and 2,4-dichlorophenol. The optimal conditions for removal were found to be pH 7 and 8, contact time of 90 minutes for phenol and 120 minutes for 2,4-dichlorophenol, at a temperature of 301 K. The Freundlich model best described the adsorption process, and the pseudo-second-order kinetics model adequately depicted the rate of adsorption.

Summary: Groundwater in eastern Thailand is contaminated with phenol and Zn2+, requiring research on the adsorption behavior of these co-contaminants for remediation design. The flood plain aquifer was found to be a dispersive aluminosilicate mineral with a SiO2 composition of 58.24%. The adsorption kinetics followed a pseudo-second-order model, and the equilibrium data were well described by Freundlich equations. The maximum adsorption capacities for phenol and Zn2+ were 24.8 mg g(-1) and 18.7 mg g(-1) at 25 degrees C, respectively.

Summary: A novel nitrogen-doped magnetic Fe-Ca codoped biochar was successfully synthesized via hydrothermal and coactivation pyrolysis method for phenol removal. The adsorption mechanism and metal-nitrogen-carbon interaction were investigated through batch experiments and various analysis techniques. The ratio of Biochar: K2FeO4: CaCO3 = 3:1:1 exhibited the best adsorption properties, with a maximum adsorption capacity of 211.73 mg/g. The Freundlich and pseudo-second-order models effectively described the adsorption data, indicating multilayer physicochemical adsorption. The developed approach in this study has the potential for organic contaminant/pollutant removal.

Summary: In this study, a sequencing batch moving-bed biofilm reactor (SBMBBR) was developed for the treatment of wastewater containing cefixime antibiotic (CFX). The effect of initial CFX concentration on various parameters was evaluated. The results showed that the SBMBBR system had good removal efficiencies for CFX, COD, and TN, but the removal efficiency decreased as the initial CFX concentration increased.

Summary: The study found that lack of safe drinking water, no access to toilet, and age significantly influence the risk of intestinal Giardia spp infection, while gender, education level, and handwashing habits have less significant effects. Additionally, there is a significant decreasing trend of intestinal Giardia spp infection over time, indicating the importance of improving personal hygiene, sanitation, and public awareness in reducing infections.

Summary: The meta-analysis investigated the concentration of potentially harmful elements in carrots and potatoes irrigated by wastewater, revealing high accumulation of Fe, Zn, and Cu in potatoes and Fe, Zn, and Ni in carrots. The total hazard quotient of PHEs in both vegetables exceeded 1, indicating a potential health risk, especially from Cd, Pb, and Cu. Continuous monitoring and control of wastewater treatment plants are recommended based on the results.
