Summary: In this study, zero valent iron (ZVI) derived from Fe-based prussian blue analogues was successfully synthesized and exhibited excellent charge transfer properties. The ZVI-2 catalyst effectively activated peroxymonosulfate (PMS), leading to rapid degradation of phenol with a removal efficiency of 94.9% within 24 minutes. The ZVI-2/PMS oxidation system showed good stability and strong anti-interference capability, making it a promising candidate for wastewater treatment.

Summary: This paper discusses the efficiency and mechanism of using nitrilotriacetic acid (NTA) as a complexing agent to enhance the zero-valent iron (Fe0)/peroxymonosulfate (PMS) system for the removal of sulfamethazine (SMZ) from water. The research results show that the addition of NTA increases the soluble iron content and the decomposition rate of PMS. Additionally, different inorganic ions, such as Cl-, have been found to affect the degradation of SMZ. In actual water bodies, the PMS/Fe0/NTA system can degrade SMZ up to 79.36%. Toxicity tests demonstrate a decrease in the inhibition rate of luminescent bacteria after degradation.

Summary: This study investigates the removal of microcontaminants (MCs) using natural solar zero-valent iron (ZVI) process at natural pH in actual matrices. The results show that the addition of sulphates and iron chelate does not significantly affect the process efficiency, while the presence of carbonates in natural water reduces the treatment time. Moreover, the solar/microspheres ZVI/hydrogen peroxide and solar/microspheres ZVI/persulfate processes achieve a moderate removal efficiency for MCs in actual wastewater treatment plant secondary effluent.

Summary: Engineered nanoparticles coated with a tunable amphiphilic copolymer were successfully delivered and retained in a target non-aqueous-phase liquid (NAPL) zone in laboratory experiments. These nanoparticles exhibited preferential binding to the NAPL and retained higher concentrations in the target zone compared to other areas. However, aggregation of nanoparticles over longer travel distances may pose a challenge for their delivery to a distant target NAPL zone.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
