Summary: In this study, activated bentonite demonstrated the highest AP uptake among the adsorbents tested, with superior adsorption capacity due to its acidic sites and pore sizes facilitating the entry of AP molecules. Activated bentonite showed a desorption activation energy higher than that of activated carbon and zeolite 13X, making it a promising adsorbent for AP removal from polluted transformer oil.

Summary: This study examined the performance of activated carbon produced from coconut shells, modified by lanthanum chloride, for Cr(VI) removal from waters. The results showed that the modified activated carbon achieved a maximum Cr(VI) removal of 95% at pH 5 and initial Cr(VI) concentration of 30 μg/L. The adsorption capacity decreased by 20% after 5 regeneration cycles. These findings highlight the potential of the modified activated carbon for effective Cr(VI) removal in water treatment.

Summary: Membrane technology is a sustainable method for removing pollutants from petroleum wastewater. However, membrane fouling caused by hydrophobic oil molecules and inorganic constituents is a challenge. In this study, a fouling resistant biopolymer-based mixed matrix membrane (MMM), incorporated with nanocrystalline cellulose (NCC), was fabricated and applied for produced water treatment. The NCC-modified membrane showed improved hydrophilicity, enhanced tensile strength, and high rejection of produced water contaminants.

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.
