Summary: Phosphate modified hydrochars (HTBs) were prepared in this study by hydrothermal carbonization of bamboo sawdust with the presence of phytic acid. The introduction of phosphate onto the biochar sorbents resulted in efficient removal of U(VI), Pb(II) and Cd(II) from various aqueous solutions, with good recyclability after multiple cycles. This work suggests a new strategy for potential application of phosphate-hydrochars in water remediation.

Summary: A novel nanoscale zero-valent iron/molybdenum disulfide (nZVI/MoS2) composite was synthesized and applied for the removal of U(VI) from water solutions. The nZVI/MoS2 composites exhibited a high surface area, uniform distribution of nZVI, and higher adsorption capacities than MoS2 due to the synergistic effect. The removal of U(VI) on nZVI/MoS2 involved cation exchange and inner-sphere surface complexation and was enhanced by the complexation of U(VI) with various oxygenated functional groups and subsequent reduction to U(IV) by Fe(0) and/or Fe(II).

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.
