Summary: In this study, cellulose acetate/graphene oxide (CA/GO) composite nanofibers were prepared and used for the removal of Cr(VI) ions from water. The impact of adsorption parameters, such as contact time, pH, and temperature, on the adsorption efficiency was investigated. The results showed that higher temperature favored the adsorption of Cr(VI) ions. The adsorption process was described by various kinetic and isotherm models. The composite nanofibers exhibited high adsorption capacity and reusability.

Summary: Porous sludge biochar (PSBC) was prepared by pyrolysis of municipal sludge using molten salt, and Fe3O4@PSBC was synthesized by chemical precipitation. The study investigated the effects of pH, sorbent dosage, coexisting ions, adsorption temperature, initial Cr(VI) ion concentrations, and adsorption time on the removal of Cr(VI) ions. The mechanism of removal was characterized using SEM, FTIR, XRD, and XPS. The results showed that Fe3O4@PSBC had a higher adsorption capacity for Cr(VI) ions compared to PSBC.

Summary: This study found that Bi2S3 nanoparticles prepared from dual sulfur sources efficiently remove Cr(VI) and Cu2+ from aqueous solutions. The selectivity and stability of the removal process for Cr(VI) and Cu2+ by BS-D were excellent. The mutual promotional effects between Cu2+ and Cr(VI) during their co-removal by BS-D were attributed to electrostatic attraction and smaller pH variation.

Summary: This article explores the possibility of adsorption of Cr (III) and Cr (VI) ions on muscovite mica for the first time. Experimental and molecular modeling studies were conducted to compare the adsorption behaviors of both ions on the mineral. The experiments investigated the effects of different operating parameters on the adsorption of the metal ions, while simulations based on Density Functional Theory (DFT) were carried out to understand the adsorption mechanisms of various Cr (III) and Cr (VI) species at different pH levels on the muscovite (001) surface.

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.
