Summary: Phosphorus pollution and its resource utilization have garnered general concern, leading to a focus on the preparation of green and renewable adsorbents free from secondary pollution. This study presents a one-step hydrothermal preparation method of Ca-modified magnetic sludge biochar (Ca-MSBC) to enhance phosphate removal. The results show that the adsorption of phosphate by Ca-MSBC is mainly controlled by chemisorption, with contributions from physical adsorption and internal diffusion. The maximum phosphorus adsorption capacity of Ca-MSBC was 89.25 mg g(-1) at 343 K, and it retained a high adsorption capacity of 70.16 mg g(-1) after nine cycles of adsorption experiments. Coexisting ions had no significant effect on the adsorption properties of phosphate. XRD, FT-IR, VSM, XPS, and N-2 adsorption/desorption isotherms confirmed that the mechanism of phosphate removal by Ca-MSBC was mainly through chemical precipitation reaction of phosphate and calcium. The findings highlight the potential application and environmental value of Ca-MSBC as a solid waste recycling material for environmental remediation.

Summary: A porous titanium phosphate (TP) monolith material was prepared for the adsorption of La(III) in mine tailwater. The adsorbent showed a stable porous structure and its adsorption capacity was not affected by solution pH greater than 2. The TP monolith material had excellent properties such as easy solid-liquid separation, good acid resistance, high adsorption capacity, selectivity for La(III), and adsorption-desorption and regeneration properties. Mechanistically, the phosphate groups on the material surface played a key role in the adsorption of La(III) by TP monolith materials.

Summary: This study presents the laboratory results of using sludge from a water treatment plant in Astana, Kazakhstan, to remove phosphate in a wastewater treatment plant. The content of chemical compounds in the sludge residue was determined, which showed a significant amount of aluminum oxide (10.8-14.6%) and iron oxide (4.58-5.31%). The results indicated that adding 50 mL of sludge to 1 L of sewage could achieve a phosphate removal rate of over 90%, and the effectiveness was primarily dependent on the sludge dosage.

Summary: The deposition of titanium dioxide (TiO2) on a copper (Cu) substrate was achieved through electrophoresis in an aqueous medium. Subsequent calcination of the samples at temperatures between 300°C and 550°C resulted in blackening and detachment of the TiO2 film from the substrate, with the formation of copper oxide at 350°C confirmed by XRD analysis. Introducing a nickel (Ni) layer improved film adhesion and prevented the formation of copper oxide, leading to a 25.54% discoloration rate of AB with the TiO2/Ni/Cu sample.

Summary: The addition of Eu to TiO2 photocatalysts showed the best enhancement in photoactivity performance for the removal of AB dye compared to Ce-TiO2 and pure TiO2 films. The optimal concentration for better electron/hole separation was found to be 1 wt% Ce or 0.1 wt% Eu doping in TiO2. EIS measurements demonstrated that Ce-TiO2(1 wt%) and Eu-TiO2(0.1 wt%) photocatalysts had lower electron transfer resistance than pure TiO2, leading to more effective separation of electron/hole pairs during photodegradation reactions.

Summary: This study prepared protective bilayer composite coatings based on polyetherimide (PEI) containing ZnO or CuO particles on mild steel (MS) using the sol-gel dip coating method. The morphology and composition of the coatings were confirmed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive spectroscopy (EDS) analysis. Attenuated total reflectance (ATR) analysis showed that the presence of oxide particles did not affect the polymer structure, while water contact angle tests revealed that PEI-CuO exhibited hydrophobic behavior, while PEI-ZnO and PEI alone showed hydrophilic behavior. Electrochemical impedance spectroscopy (EIS) analysis demonstrated that the PEI-CuO coating had impedance values above 5 x 10(5) Omega.cm(2) after immersion in NaCl for 8 days, representing a protective efficiency greater than 99%.

Researchers have successfully developed shaped photocomposites by combining these materials with acrylate polymer through a green and rapid photo-polymerization process under visible light. These photocomposites exhibit excellent polymer robustness, stability, and malleability, while maintaining remarkable photo-catalytic properties. Among them, the MIL-100(Fe)/polymer composite was found to be the most efficient photocatalytic system with high reusability and consistent degradation percentages in 10 catalytic cycles.

Summary: Cerium and europium-doped titanium nanotubes (Ce and Eu-TNTs) were synthesized through one-step electrochemical anodization. Scanning electron microscopy revealed that Ce and Eu-TNTs had less organized and more spaced nanotubes compared to pure TNTs. XRD analysis confirmed that the doping did not change the crystalline phase of the nanotubes. EIS measurements showed that Ce/Eu-doped TNTs had lower electron transfer resistance, indicating efficient separation of photogenerated electron/hole pairs. Photodegradation experiments demonstrated that Ce-TNTs (0.5 mM) and Eu-TNTs (2 mM) exhibited the highest enhancement in removing AB, with reaction rates of (k(app) = 0.026 min(-1), t(1/2) = 19 min) and (k(app) = 0.020 min(-1), t(1/2) = 20 min), respectively, under initial pH = 3 and C-AB = 10 mg.L-1, compared to (k(app) = 0.014 min(-1), t(1/2) = 35 min) for pure TNTs. The adsorption efficiency in the dark after 30 min was enhanced by Ce and Eu-doping, reaching a maximum of 52.08% for Eu-TNTs (2 mM) compared to only 31.11% and 32.96% for Ce-TNTs (0.5 mM) and pure TNTs catalyst, respectively.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
