Summary: The main focus of this work is to change inert sand into a reactive material by adding layered double hydroxide nanoparticles to its surfaces. Surfactant, chicken eggshells, and alum were used to create these nanoparticles. The modified sand showed high efficiency in removing amoxicillin from water, with a maximum sorption capacity of 43.642 mg/g. The structure of coated sand significantly changed due to the formation of a plate-like layer made up of loosely aggregated micrometric plates caused by LDH nanoparticles, resulting in increased removal of antibiotics.

Summary: The widespread use of amoxicillin for treating common diseases has raised concerns about its presence in sewage and its impact on the environment and human health. This review discusses the ways amoxicillin enters the environment and its potential effects. Detection methods and remediation techniques for its removal from wastewater are also discussed. Advanced oxidation processes and constructed wetlands have been found to be the most and least applied methods for remediation, respectively.

Summary: Carbon dots enhanced the photosynthetic activity of Chlorella under antibiotic stress, leading to a significant increase in specific growth rate, photosystems II activity, and antibiotic removal. The toxicity of residuals was eliminated, while the removal of nitrogen and phosphorous increased, as well as the production of pigments, lipids, and proteins. This study proposed a new strategy for coupling microalgal bioresource production and toxic wastewater purification using CDs.

Summary: This study investigated the potential of a Trichoderma strain (Trichoderma pubescens DAOM 166162) isolated from activated sludge for the treatment of amoxicillin (AMO) containing wastewater. The study revealed that the strain's removal of AMO was facilitated by the secretion of extracellular polymeric substances (EPS) with a higher protein percentage. The primary degradation pathway of AMO by the strain was the hydroxyl group uncoupling the lactam ring and subsequent hydrolysis in an alkaline environment.

Summary: In this paper, a novel sensing strategy for detecting amoxicillin (AMX) based on photoinduced electron transfer (PET) is reported. The AMX molecule is activated by ultraviolet irradiation, resulting in a lower energy product that acts as an electron donor in the CPE system. The electrochemical response is improved by exposing the homogeneous solution to UV photoirradiation. This low-cost and high sensitivity method has been successfully applied to the determination of AMX in tap water and wastewater samples.

Summary: A novel Bi2WO6/nano-ZnO hybrid material was synthesized using a simple two-step hydrothermal method for photocatalytic degradation of amoxicillin in wastewater under visible light. The hybrid material, composed of many nanosheets in a layered structure, exhibited significantly improved photocatalytic activity compared to pure Bi2WO6 and nano-ZnO, with the Bi2WO6/nano-ZnO sample at a molar ratio of 1:3 showing the highest activity. The enhancement in photocatalytic activity is attributed to the reduction of band gap energy caused by the heterostructure formed by the two semiconductors, enabling effective separation and inhibition of recombination of photo generated charge carriers.

Summary: This study found that the availability of arsenic (As) in soil is closely related to the presence of iron (Fe) oxides and humic acid (HA). However, the relationship between Fe oxides and HA and As species is not well understood. The experiment showed that As(V) is mainly distributed to certain bound forms of Fe and Al oxides, while As(III) is mainly found in the residual fraction. The addition of HA and green synthesized Fe oxide nanoparticles (FeNPs) affected the distribution of As species in the soil, with HA/FeNPs treatment increasing As(V) in certain bound forms and decreasing As(III) in the residual fraction. The study proposed a mechanism involving the combination of HA and FeNPs to explain the redistribution of As species in the soil.

Summary: Bio-reduced graphene oxide (B-rGO) synthesized by Lysinibacillus sp. can simultaneously remove triclosan (TCS) and Cadmium (Cd(II)), with higher adsorption capacities compared to commercially available reduced graphene oxide (C-rGO). The presence of extracellular polymeric substances (EPS) on B-rGO surface plays a crucial role in enhancing the removal of contaminants. The adsorption mechanism of TCS involves 7C-7C interactions and hydrogen bonding, while Cd(II) is removed through a combination of electrostatic interactions and chelation/complexation.

Summary: Recycling rare earth elements (REEs) from secondary waste sources like REEs mine wastewater is a sustainable approach that allows for waste reuse and wastewater processing. In this study, environmentally friendly, sustainable, and low-cost green reduced graphene oxide (G-rGO) was prepared using green tea extract. The comparison between G-rGO and commercial reduced graphene oxide (rGO) showed that G-rGO had a much higher efficiency in adsorbing Y(III), indicating a synergistic adsorption between the capping layer of G-rGO and rGO alone. The adsorption mechanism of Y(III) by G-rGO was proposed to involve electronic complexation, electrostatic adsorption, and ion exchange. Furthermore, G-rGO demonstrated high adsorption efficiencies for Y(III), Ce(III), and Zn(II) in mine wastewater.

Summary: By optimizing the synthesis conditions of Fe/Mn nanoparticles (Fe/Mn NPs) using response surface methodology (RSM), the efficiency of Fe/Mn NPs in removing oxytetracycline (OTC) and copper ion (Cu(II)) from livestock and poultry farming wastewater was significantly increased. The Fe/Mn NPs were found to have elliptic shape with amino, carboxyl, and hydroxyl functional groups on the surface, maintaining a high negative charge density between pH 1 and 11. A removal mechanism based on a combination of complex-bridging effect, pore-filling, hydrogen bonding, surface complexation, ion exchange, and electrostatic attraction was proposed. In swine wastewater experiments, Fe/Mn NPs achieved a removal rate of 99.9% for OTC and 55.6% for Cu(II).

Summary: This study introduces a green sustainable carbon@nano-zero-valent iron composite (C@nZVI) derived from biosynthesis for removing Pb(II) and Zn(II) heavy metal ions from mining wastewater. The C@nZVI exhibits high removal capacities for Pb(II) and Zn(II) of 98.37 and 26.38 mg center dot g 1, respectively. The adsorption of both Pb(II) and Zn(II) onto carbon and iron oxides was confirmed, followed by the reduction of Pb(II) to Pb(0) by nZVI with the assistance of biomass-derived carbon. The Langmuir and pseudo-second-order kinetic models were found to best fit the adsorption process. Furthermore, C@nZVI also demonstrated high removal efficiencies for other contaminants such as As, Cd, and Sb, indicating its great potential for environmental remediation applications.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
