Summary: Iron scraps were found to increase nitrification efficiency at low temperatures by 15.7%, compared with the PVA-SA embedded balls by 27.6%. Among these groups, the iron scrap-based group demonstrated the best anti-shock capacity with minimal fluctuations under changing conditions. Nitrosomonas was identified as the dominant bacterial genus for both immobilization materials. The additional costs of iron scraps and PVA-SA embedded balls were found to be minimal per ton of treated domestic wastewater. In conclusion, iron scraps offer significant advantages in terms of low costs, availability, and anti-shock capacity, making them a promising candidate for enhancing nitrification of domestic wastewater at low temperatures.

Summary: This study investigated the removal of polyamide microplastics from wastewater using electrocoagulation. The combination of iron anode and aluminum cathode (Fe-Al) exhibited the highest removal efficiency. The removal efficiency of microplastics increased with higher applied voltage and electrolyte concentration. The optimized conditions for polyamide removal were using Fe-Al electrodes, with a plate spacing of 2.5 cm, an applied voltage of 10 V, an initial pH of 7, and an electrolyte concentration of 0.02 mol/L. This study highlights the potential of electrocoagulation for microplastics removal and provides insights for operational parameter optimization.

Summary: In this study, a three-electrode electrolysis system was used to synthesize nickel hydroxide-iron hydroxide/graphene hybrid, which showed superior oxygen evolution reaction (OER) performance. The introduction of iron (Fe) not only converted the inactive alpha-Ni(OH)2 into more active beta-Ni(OH)2, but also improved the electrical conductivity and electrochemically active surface area (ECSA) of the obtained hybrid material. This work provides a novel and facile method for highly efficient OER.

Summary: Polymeric aluminum organophosphates are nanostructured aluminum-based compounds that combine organic and inorganic materials. They have attracted attention for their ability to improve the mechanical properties, lightweight, and thermal properties of composite materials. The potential of these compounds for fire-retardant materials has been demonstrated through studies. In this research, epoxy resin composites were created using aluminum oxide hydroxide and aluminum-organophosphorus hybrid materials.

Summary: The dissolution of aluminum hydroxide was studied to recover fluoride and neutralize acidity. Dissolving aluminum hydroxide with sodium carbonate reduced the treatment cost by 45% compared to using other aluminum salts. Two types of aluminum hydroxide with different crystallinity were investigated, showing different effects on dissolution.

Summary: Polymer flooding is a cost-effective method for enhanced oil recovery. In this study, a hyperbranched nanowire (O-20 @PAM@CNTs) was successfully synthesized for polymer flooding, showing excellent viscosification and temperature resistance. The hybrid carbon nanotubes (CNTs) in O-20 @PAM@CNTs provided a hyperbranched structure and improved the association between polymer chains. Core flooding experiments demonstrated that O-20 @PAM@CNTs enhanced oil recovery more effectively than O-20 @PAM, indicating its better application in enhanced oil recovery.

Summary: The study focuses on improving the neutralization process of sulfate-based REE pregnant leach solutions with a specific emphasis on Fe and Al removal. Tests show that using Ca(OH)2 leads to higher REE loss, but calcium-based reagents are still economically beneficial due to cost-effectiveness. A two-step impurity removal process is proposed to enhance the efficiency of REE processing, involving neutralization and acid leaching steps to recover lost REE.

Summary: This study presents a strategy for the treatment of concentrated fluoride in acidic wastewater by coupling zero-valent iron (ZVI) with Ca(OH)(2). ZVI reduces the fluoride concentration from 12,000 to 3980 mg L-1 through the in-situ growth of porous FeF2.4H(2)O shell on its surface and adsorption. The residual fluoride is then further decreased to 6.74 mg L-1 via precipitation with Ca(OH)(2). The co-precipitation of iron ions from ZVI forms magnetite, enhancing fluoride removal and enabling solid-liquid separation by a magnetic field. The application prospect of this coupling strategy is verified in reducing the concentrations of fluoride and other heavy metals in real smeltery wastewater.

Summary: This study introduces the use of iron-borne clay mineral as a reduction agent to mitigate nitrite (NO2-) concentrations in anoxic zones. The research found that oxygenated and reduced montmorillonite (SWy-2) can effectively oxidize nitrite under neutral pH conditions. The reduction of nitrite occurred within the first 30 minutes of the reaction, with the amount of Fe(II) consumed decreasing over time and the byproducts increasing. This concept of oxidation of nitrite through reduced iron-borne clay mineral may be applicable to other reduction/oxidation reactions that reduce active pollutants effectively.
