Summary: The use of activated orange peel as a precursor for HLPC-PO4 material synthesis resulted in a highly efficient adsorbent for the removal of U(VI) in radioactive wastewater. The material showed strong adsorption capacity and selectivity for U(VI), with a high retention of adsorption capacity even after multiple cycles.

Summary: Ultrasound-assisted synthesis of Mn/Co-MOF nanomaterial was used to capture uranium from aqueous solutions. The results suggest that cobalt ions were partially replaced by manganese ions during the synthesis process, forming manganous oxide particles loaded on the surface of Mn/Co-MOF. The optimal conditions for immobilizing U(VI) were systematically studied, and it was found that the adsorption isotherms of Mn/Co-MOF for uranium suit the Langmuir isotherm model.

Summary: In this study, a novel lignin-derived biochar (AL/BC) with high surface area and abundant functional groups was developed and used as an adsorbent for efficient U(VI) capture. The optimized AL/BC-600 exhibited ultrahigh adsorption capacity for U(VI) and strong anti-interference ability in the presence of various common cations and anions. Furthermore, AL/BC-600 showed high tolerance even under strong irradiation. After multiple cycles of adsorption and desorption, the adsorption efficiency and desorption rate of AL/BC-600 remained high. Therefore, this study provides a green and simple process for synthesizing a highly efficient adsorbent for U(VI) capture.

Summary: In this study, a novel biocomposite (A/PBC) was produced by loading Alcaligenes faecalis on phosphorus-rich biochar (PBC), which significantly improved the adsorption effect on U(VI). A/PBC had lower phosphorus release into the solution, nearly 100% U(VI) removal ratio, and only a 1.98% decrease after 5 cycles. A/PBC converted soluble phosphate into insoluble metaphosphate minerals and extracellular polymeric substances (EPS) to form a biofilm attached to the PBC surface, increasing the abundance of acidic functional groups and promoting U(VI) adsorption.

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.
