Summary: The presence of emerging micropollutants in the environment has become a significant threat to human health and aquatic ecosystems. These micropollutants, including pharmaceuticals and pesticides, enter the environment through human activities and can be found in various water sources. Conventional wastewater treatment plants are not effective in removing a large portion of these pollutants, particularly pharmaceuticals, leading to continuous contamination of freshwater systems. In this study, the effectiveness of TiO2 as a photocatalyst combined with Na2S2O8 as an oxidant was evaluated for the treatment of wastewater effluent contaminated with pharmaceutical residues. The results showed that this solar heterogeneous photocatalysis method significantly enhanced the removal of pharmaceuticals from the wastewater effluent. However, the presence of dissolved salts and organic carbon in the wastewater effluent slowed down the degradation process. The study also found that macrolides had the longest degradation time in wastewater effluent compared to other compounds studied. This methodology is particularly relevant in water-scarce areas with abundant sunlight, such as the southeast of Spain.

Summary: In recent years, nanotechnology has emerged as an important field for the synthesis of nanoparticles using biological processes. Mushroom extract is a prominent method in biological synthesis due to its abundance of biologically active compounds. In this study, Zinc Oxide nanoparticles (ZnO NPs) were successfully synthesized using Daedalea sp. mushroom extract. The nanoparticles exhibited irregular morphology, with an average size of 14.58 nm. Various analytical techniques confirmed the synthesis of ZnO NPs, which were then tested for biocompatibility, antifungal, antileishmanial, and antibacterial activities. The ZnO nanoparticles showed strong antibacterial effects against both gram-positive and gram-negative bacteria, as well as high antifungal activity against Aspergillus niger fungus.

Summary: Pollution of the environment, particularly water resources, is a major challenge due to emerging contaminants of anthropogenic origin, such as pharmaceuticals, endocrine disruptors, and pesticides. Techniques based on polymer inclusion membranes (PIMs) show promise in removing these contaminants from aqueous solutions, including wastewater, due to their high efficiency, versatility, ease of preparation, and selectivity. This review discusses recent developments in using PIMs to remove emerging contaminants and synthetic dyes from aqueous solutions, with a focus on improving the effectiveness and selectivity of PIMs for wider future use.

Summary: Adsorbents, including sugarcane bagasse fly ash and traditional activated carbon, were studied for the removal of fipronil, a pesticide, from water. The results showed that sugarcane bagasse fly ash achieved a high removal efficiency of 80% for fipronil, even without prior treatment. The study also found that the Freundlich model described the adsorption data better than the Langmuir model, and the method developed for fipronil adsorption is cost-effective and enables the reuse of sugarcane industry waste.

Summary: Selective removal of one ligand in mixed-ligand MOFs creates hierarchical pore architectures with improved adsorption capacity for glyphosate removal from water. The Ti-OH groups resulting from ligand removal serve as effective anchor points for glyphosate uptake. The introduction of additional mesopores has significantly increased the adsorption capacities, making these MOFs among the best-reported adsorbents.

Summary: The use of sol-gel synthesized calcium oxide nanoparticles as catalyst can effectively degrade dyes, with a removal efficiency of 98%. The degradation efficiency is influenced by time, initial dye concentration, catalyst load, pH, and ionic strength. The study found that the degradation kinetics best fit the Langmuir-Hinshelwood, first order, and pseudo first-order models. Quantum chemical calculations revealed that the degradation involved adsorption, deformation/degradation, and desorption processes.

Summary: This study used a statistical physics approach to investigate the adsorption of pesticide glyphosate on modified carbon nanotubes via green synthesis. The results showed that the adsorption of glyphosate occurs through the formation of a monolayer and is characterized by only one energy when interacting with MWCNT/MPNs-Fe. The study also evaluated the geometric and energetic aspects of the system and found that the adsorption is an exothermic process involving a physical interaction mechanism. Additionally, the results indicated that the MWCNT/MPNs-Fe adsorbent promotes pesticide adsorption by interacting with metallic iron nanoparticles present on the adsorbent surface.

Summary: Despite the inconsistent data representation in various published reviews, this review emphasizes the importance of desorption and regeneration compared to the adsorption stage. Different adsorbents, such as graphene, carbon nanotubes, activated carbon compounds, clays, and polymer adsorbents, are categorized and studied for their desorption and regeneration abilities. The pH, dose, concentration, adsorption ability, and cost of the adsorbents are examined for further analysis. The study also evaluates the recovery efficiency and reuse potential of the adsorbents through the desorption process. The highest adsorption capacity is observed in graphene-based and activated carbon materials, while carbon nanotubes and polymer-based adsorbents show lower and varying adsorption capacities.

Summary: This study used sorghum straw to prepare biochar as an adsorbent for ammonium adsorption in order to solve the problem of sorghum straw utilization and ammonium removal from water. The results showed that sorghum straw biochar had a higher adsorption capacity compared to sorghum straw. The optimal adsorption capacity was achieved at a pyrolysis temperature of 300 degrees C. The pH range of 6-10 and a dosage of 2.5 g/L were found to be favorable for adsorption. The adsorption process followed pseudo-second-order kinetics and Langmuir isotherm adsorption models. The maximum ammonium adsorption capacity of sorghum straw biochar at 45 degrees C was 7.09 mg/g, which was 7.60 times higher than that of sorghum straw. The adsorption of ammonium by both sorghum straw and sorghum straw biochar was mainly a chemical adsorption process. Furthermore, sorghum straw biochar showed good regeneration performance after three adsorption-regeneration cycles. This study suggests that sorghum straw biochar could potentially be applied for ammonium-containing sewage treatment to achieve resource recycling.

Summary: Calcined Ca-Al hydrotalcites were prepared using clean method (Ca-LDO-1) and traditional co-precipitation method (Ca-LDO-2). Ca-LDO-1 showed better adsorption performance for glyphosate due to its higher specific surface area and pore volume compared to Ca-LDO-2. The adsorption kinetics and thermodynamics of glyphosate by Ca-LDO-1 were found to be consistent with pseudo-second-order kinetic equation and Langmuir isotherm equation.
