Summary: The potential use of magnetic nanopowder for phenol adsorption mobilised on natural grain carbon foam from an aqueous solution was studied. A magnetic nanopowder was synthesised by dissolving an iron sponge in nitric acid to produce iron nitrate, which was added to a natural grain mixture. The effects of initial concentration, time, and TEM characterisation on the synthesised carbon foam were investigated. Kinetic and equilibrium studies showed that the phenol adsorption increased with higher iron content and initial concentration, and the Temkin model provided the best fit to the experimental data. Carbon magnetic nanopowder is considered an outstanding pollutant absorber in environmental investigations due to its exceptional physical and chemical properties.

Summary: In this study, a supramolecular hydrogel was successfully synthesized and demonstrated excellent adsorption performance for phenol in wastewater treatment. The introduction of a modified cellulose base material increased the mechanical strength of the hydrogel. Additionally, the adsorption kinetics of phenol on the supramolecular hydrogel followed a quasi-second-order reaction, and the adsorption isotherm conformed to the Langmuir adsorption isotherm.

Summary: Attapulgite (ATP) and its organically modified derivatives have been studied for potential environmental remediation applications, resulting in the synthesis of a composite hydrogel capable of adsorbing heavy metal ions Ni(II) and organic pollutant phenol. The modified ATP and composite hydrogel showed good adsorption properties for Ni(II) ions and phenol. Double-modification proved to be the most effective method for phenol adsorption, with optimal adsorption capacity obtained on PAAm/CTAB-HA-ATP hydrogel.

Summary: We reveal the mechanism for the strong reinforcement of attractive nanofiller-hydrogel composites. The attractive interactions induce a local increase in the gel density around the nanofillers, which leads to the formation of a percolated network. This network constrains the gel displacement and enhances stress coupling, resulting in a global reinforcement of the composite.

Summary: The study found that adsorption of resazurin on PAA hydrogels improved its stability and reliability in viability assays for both bacteria and mammalian cells. For E. coli inoculums higher than 1.0 x 10(4) CFU/mL, there was no significant difference in the reduction rates of resazurin adsorbed on hydrogels compared to resazurin free in the growth medium, but the stability of resazurin was higher when adsorbed on hydrogels.

Summary: A Moroccan clay enriched with silica and alumina was used to adsorb phenol from aqueous solutions. Various characterization techniques were employed to examine the physical and chemical properties of the clay. The adsorption kinetics were rapid and followed the pseudo-second-order model, with an impressive adsorption capacity near 97 mg/g. Investigation into the interaction mechanism between phenol and clay revealed the nucleophilic sites in phenol engaging with the positive sites of the silica and alumina phases. The clay also showed potential for reuse in pottery production without significant alterations in flexural strength.

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.
