Summary: A new nanocomposite, A-CNF/DT, was successfully synthesized and used for the removal of methylene blue and indigo carmine dyes from water. Langmuir and Sips isotherm models well fitted the adsorption isotherm data of methylene blue and indigo carmine onto A-CNT/DT, respectively. The experimental kinetic data showed good agreement with pseudo-first order model (for the adsorption of methylene blue) and pseudo-second order model (for the adsorption of indigo carmine) onto A-CNT/DT. Thermodynamic parameters indicated that the adsorption of methylene blue was endothermic, while the adsorption of indigo carmine was exothermic. Monte-Carlo calculation method revealed both polar and nonpolar interactions between the dye molecules and the A-CNT/DT surface. Overall, the synthesized A-CNT/DT proved to be an efficient adsorbent for the removal of dyes from aqueous solutions.

Summary: The 2D few-layered Ti3C2Tx MXene nanosheets were prepared through etching and delamination of aluminium layers from the Ti3AlC2 MAX phase. The electroactive polyamide (EPA)/Ti3C2Tx MXene nanocomposites (NCs) containing various amounts of MXene were synthesized via in-situ oxidative coupling polymerization. The NCs showed improved physical properties such as electrical conductivity, thermal stability, and adhesion strength due to the close interaction between EPA and MXene. The addition of Ti3C2Tx MXene did not affect the surface roughness and water contact angle of the EPA matrix. The NCs coated samples exhibited improved tribological properties, and the corrosion study demonstrated excellent corrosion protection ability of EPA/Ti3C2Tx MXene NCs containing 1.2 wt% MXene.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
