Summary: The study found that the hydraulic conductivity of organoclays with added surfactants increased by about two orders of magnitude in percolation experiments. These organoclays showed good adsorption capacity for the antibiotic AMX, but the increased permeability led to a shorter interaction time with the pharmaceutical, resulting in ineffective removal of the antibiotic.

Summary: In this study, the nanostructure of phenol-intercalated montmorillonite was investigated using molecular dynamics simulation. It was found that the interlayer swelled nonlinearly upon intercalation of phenol, and the MV cations and phenol molecules were tilted and roughly parallel to each other. The parallel orientation in the interlayer was identified as the key factor for the color reaction.

Summary: Graphene oxide (GO) was successfully synthesized and characterized, showing high potential for the adsorption of Cd (II) and Pb (II) due to its high adsorption capacity, rapid intake, and great regeneration performance. Adsorption experiments indicated that increasing adsorbent mass improved the removal efficiency of Cd (II) and Pb (II), with Freundlich isotherm better describing Pb (II) adsorption and linear behavior observed for Cd (II) isotherm. Kinetic data were satisfactorily described by pseudo-first order model for Cd (II) and pseudo-n order model for Pb (II), and GO exhibited efficiency of over 90% in five regeneration cycles.

Summary: This paper describes the development of a recirculating photocatalytic reactor with UV-C radiation and TiO2 supported on polystyrene films obtained from post-consumer packaging. The dye mixture of brilliant blue and erythrosine used in the food industry was treated by UV/H2O2, UV/H2O2/TiO2-suspension, and UV/H2O2/TiO2-supported processes. A degradation of 100% was achieved after 390 min for 9.2 mmol.L-1 of H2O2 when using the TiO2 supported (333 mg.L-1). The catalytic and non-catalytic mathematical models had a good fit for the experimental data, in the case of the recirculating photocatalytic reactor operating a first-order catalytic reaction. The material used as a support is an easily available residue. The good performance of the reactor developed suggests that it could be used in the degradation of organic components.

Summary: This study investigates the use of smectite clays for removing benzene, toluene, and metal ions from petrochemical wastewater. The clay was modified with sodium carbonate to enhance its adsorption and cation exchange properties. The results show that the modified clay had a mesoporous structure and increased exchangeable ions. The Langmuir-Freundlich isotherm was the most representative, with adsorption capacities for benzene and toluene of 7.28 and 7.39 mg g(-1). The ionic exchange model was applied for the removal of Cu(II) and Pb(II), with capacities of 0.99 and 1.10 mg g(-1) respectively. The kinetic constants for benzene and toluene were 0.0016 and 0.019 L mg(-1) min(-1). The modified clay showed kinetic constants of 0.049 and 0.063 L mg(-1) min(-1) for Cu(II) and Pb(II) respectively. The results demonstrate the high efficiency of the modified clay in removing BTEX and heavy metals from wastewater.

Summary: An agar-graphene oxide hydrogel was successfully prepared to remove Cd (II) and Methyl Violet (MV) from water. The hydrogel was characterized using SEM and EDS, showing a 3D-disordered porous microstructure mainly composed of C and O. The adsorption experiments fitted well with Langmuir, Freundlich and Sips isotherm models, and the kinetics were satisfactorily described by pseudo-order models. Regeneration studies demonstrated the outstanding reuse capacity of the adsorbent. This study highlights the potential of the hydrogel as a feasible and reusable adsorbent for Cd (II) and MV removal from water.

Summary: In this study, Ni/gamma-Al2O3 (Ni/Al) and Ni/La2O3-gamma-Al2O3 (Ni/La-Al) catalysts were synthesized using the all-in-one method and applied to dry methane reforming. The results showed that the Ni crystallite size was smaller for the catalyst promoted by La, indicating better dispersion of its active phase. The monoliths exhibited a higher conversion rate compared to the powdered catalysts. Deactivation of the monoliths was studied using residual activity deactivation models (DMRA) and a good fit was achieved with high accuracy. The deactivation level of the structured systems was found to vary with the WHSV values. Finally, CO2 regeneration showed superior results compared to H-2 regeneration for the catalysts.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
