Summary: Activated-carbon-containing pellets were prepared by direct chemical activation of sawdust with clays as a binder. The pellets were coated with hydroxyapatite nanoparticles to improve adsorption capacity for heavy metal ions. The adsorption process followed the pseudo-second-order kinetic model and the adsorption isotherm of Pb(II) fitted the Langmuir model. Desorption efficiency was improved by lowering the pH of the acid used, and the pellets could be regenerated through a desorption-rinsing-re-coating procedure. The regeneration process did not affect the adsorption of Pb(II) but reduced the compressive strength of the pellets.

Summary: In this study, the long-term performance of the GAC particle electrode oxidation process (GAC EOP) on amoxicillin (AMX) removal and activated carbon regeneration was investigated. The results showed that the GAC electrode had a more stable physisorption and chemisorption capacity compared to the GAC adsorption process (GAC ADS). The electrochemical regeneration effect ensured the stable chemisorption capacity of the GAC EOP system, resulting in a continuous increase in AMX removal efficiency during the 50 consecutive runs.

Summary: One of the main challenges of absorption-based CO2 capture is the high energy penalty during solvent regeneration. The addition of a solid acidic catalyst can optimize CO2 desorption at low temperatures and reduce the regeneration penalty. Metal-supported activated carbon catalysts were synthesized and evaluated, showing significant improvement in amine solvent regeneration. Using scalable and inexpensive materials can greatly reduce energy requirements for CO2 capture, advancing catalytic CO2 capture towards industrial implementation.

Summary: The study reveals that carbon consumption in activated carbon technology for flue gas purification primarily originates from the reaction of H2SO4 and C, as well as the thermal decomposition of oxygen-containing functional groups. Interestingly, carbon consumption does not increase as SO2 concentration rises. Additionally, in the cyclic adsorption-regeneration process, carbon consumption is significantly higher in the first cycle due to the decomposition of functional groups within the activated carbon itself.

In this study, three CMPs-based composite membranes were rapidly fabricated with adjustable size using unidirectional diffusion synthesis. The microstructural design enhanced the rejection rates of the membranes and they showed strong hydrolytic resistance, thermal stability, and acid-base resistance. Electrostatic adsorption and the adjustable microstructures significantly varied the repellence of the membranes to different charged molecules.

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.
