Summary: The aim of this study was to synthesize low-cost material activated carbon and magnetize it with CoFe2O4 nanoparticles to evaluate its efficiency in removing cephalexin from water. The results showed that the removal efficiency of cephalexin increased with longer contact time and higher adsorbent dose, but decreased with higher pH and initial concentration of cephalexin. Optimal conditions for cephalexin removal were pH = 3, time = 30 min, antibiotics concentration = 50 mg/L, and adsorbent dose = 2 g/L. The cephalexin adsorption process followed the Freundlich isotherm and pseudo second-order kinetics.

Summary: In this study, the removal of dye ADMI from raw textile wastewater was investigated using magnetic multi-walled carbon nanotubes-loaded alginate. The key factors, including pH, adsorbent dose, and contact time, were optimized using response surface methodology-based central composite face-centred design. The adsorbents were characterized using various techniques. The developed model fit well with the experimental data, and under the optimized conditions, a high removal efficiency and ADMI adsorption capacity were achieved. The adsorption process was found to be monolayer and chemical in nature. The adsorption mechanism could be explained by the presence of negatively charged carboxyl and hydroxyl groups on the surface of the adsorbent.

Summary: Modified magnetite chitosan with silver nanoparticles was synthesized and tested for the removal of cationic and anionic dyes in aqueous solutions. The optimal pH for removing anionic dyes was found to be 4.0, while pH 8.0 was optimal for removing cationic dyes. The synthesized nanosorbents showed high adsorption capacity and regeneration capability for both dyes.

Summary: This paper summarizes the influences of minerals and organic matter on the adsorption, degradation, and plant uptake of sulfonamides (SAs) in soil. Minerals effectively adsorb SAs through mechanisms such as cation exchange, complexation, hydrogen bonding, and cation bridging, while soil organic matter significantly increases their adsorption. Soil organic matter reduces the mobility of SAs in the environment, while dissolved organic matter increases their availability.

Summary: Currently, various heterogeneous catalysts have been synthesized to activate persulfate (PS) and generate reactive species for the degradation of antibiotics in water. However, there is a lack of systematic understanding of the relationship among catalyst active sites, PS activation pathway, and antibiotic degradation. This review summarizes the impact of metal-based, carbon-based, and metal-carbon composite catalysts on antibiotic degradation by activating PS. Different oxidation pathways are induced by metal and non-metal sites, which can effectively attack specific bonds in antibiotics and cleave them.

Summary: In Egypt, the consumption of pharmaceuticals has greatly increased due to population growth and unrestricted sales. A study was conducted on the occurrence and fate of common pharmaceutical active compounds (PhACs) at a sewage treatment plant in Giza, Egypt. The levels of PhACs were monitored throughout different treatment stages and in dewatered sludge. The results showed that biodegradation and adsorption were the main removal mechanisms for the studied PhACs.

Summary: The study measured the levels of 16 PAHs in soft drinks and non-alcoholic beers using the MSPE/GC-MS method and assessed their health risks. The concentrations of 16 PAHs in soft drinks were 0.702 ppb (n-ary sumation 16PAH) and 0.196 ppb (n-ary sumation 8PAHs), while in non-alcoholic beers, they were 1.315 ppb (n-ary sumation 16PAH) and 0.288 ppb (n-ary sumation 8PAHs). The Monte Carlo simulation results showed that the THQ 95th percentiles for soft drinks were 9.497E-04 (adults) and 2.221E-03 (children), and for non-alcoholic beers, they were 3.341E-03 (children) and 1.430E-03 (adults).

Summary: Understanding the distribution of soil organic carbon and nitrogen (OC(N)), cation exchange capacity (CEC), and specific surface area (SSA) in different soil particle sizes is important for studying soil fertility and properties. This study investigated the distribution characteristics of OC(N), CEC, and SSA in yellow-brown soil particles under different methods. As particle size decreased, soil OC(N), SSA, and CEC content gradually increased. There were significant linear relationships between OC and ON, SSA and equivalent diameter, and CEC and SSA. These findings provide valuable data support and a theoretical basis for understanding soil properties.

Summary: This study developed a method to catalytically oxidize and degrade Ceftriaxone (CTX) from aqueous solution using the heterogeneous system O-3/UV/Fe3O4@TiO(2). Through optimization of operational parameters, high removal efficiency of CTX and reduction of total organic carbon (TOC) were achieved. The reuse potential of Fe3O4@TiO2 was proven with high removal efficiency of CTX and TOC after six consecutive catalyst uses. OH degrees played a major role in the photocatalytic degradation of CTX. Integration of O-3/UV/Fe3O4@TiO(2) demonstrated excellent CTX removal performance and can be considered a promising technique for decontamination of polluted waters.

Summary: In this study, a methodology based on Fuzzy AHP-TOPSIS was proposed to select the best colour treatment process using carbon-based adsorbent materials. The criteria for decision making, including cost, safety, accessibility, reuse, and adsorption capacity, were prioritized based on the experts' opinions. The performance of eight carbon-based adsorbent materials in colour removal was evaluated using the Fuzzy TOPSIS decision matrix. Furthermore, the key factors in the treatment of real textile wastewater using PAC were investigated and optimized. The findings indicate that colour adsorption using PAC is feasible, spontaneous, and endothermic.

This review examines the presence, concentrations, and types of antibiotics in various waste treatment plants, natural water bodies, and hospital wastewaters over the past 10 years. The most frequently detected antibiotics are sulfonamides, followed by macrolides, trimethoprim, quinolones, and tetracyclines. Future research on the development of more effective technologies for antibiotic removal is recommended.

Summary: This study evaluates the effectiveness of Parkia speciosa pod as a biosorbent for removing lead(II) from wastewater. The optimized conditions for maximum biosorption capacity were found to be 55 degrees C, 79.42 mg/L concentration, 4.47 pH and 2 g/L dosage. The kinetics of lead(II) biosorption followed the pseudo-second-order model and the equilibrium correlated well with the Langmuir isotherm. The results demonstrate that Parkia speciosa pod is a sustainable and effective biosorptive material for lead(II) remediation.

Summary: In this study, uniform Fe3O4@Na2Ti3O7 (FNTO) nanoleafs with wider layer spacing and fluent Na-ion exchange effect were synthesized through a hydrothermal reaction, and FNTO-CN composites were prepared with folic acid as C and N sources. When tested as working electrodes in a half-cell versus Na metal, both FNTO and FNTO-CN exhibited high-capacity densities and stability, showing potential for developing high-performance anode materials. This interlayer engineering with folic acid as a dual C and N source may serve as a useful tool for modifying the properties of anode/cathode materials.

The results showed that both BC-500 and BC-700 had high TC removal rates, with different maximum adsorption capacities, and were well described by pseudo-second order kinetics. Even after multiple cycles, the biochar still maintained satisfactory removal efficiencies, mainly through hydrophobic interactions and pi-pi electron donor acceptor interactions.
