Summary: This study investigated the adsorption process of o-DCB onto ACs and modified CNTs from the aqueous phase. It was found that carbon adsorbents are effective in removing o-DCB, with ACs showing higher regenerative abilities compared to CNTs. The modifications of CNTs improved their adsorption properties for o-DCB, but impacted the effectiveness of the regeneration process.

Summary: This study examines the adsorption kinetics of activated carbon (AC) adsorbent materials produced from a by-product of African palm processing. The textural characteristics of the adsorbent solids were determined through N-2 physisorption, revealing BET areas between 721 and 1334 m(2)g(-1) and micropore volumes between 0.33 and 0.55 cm(3)g(-1). FTIR was used for chemical characterization, and CO2 adsorption was measured, showing values between 175 and 274 mg·g(-1). The kinetic study suggests that the intraparticle diffusion model best describes the physisorption process.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
