Summary: The purpose of this study is to investigate the operating conditions of a physicochemical pretreatment process for lignocellulosic biomass using homogeneous acid catalysts. Four parameters were examined: moisture content, acid catalyst, type of biomass, and reactor morphology. Different types of biomass were processed with sulfuric acid in a meat grinder, and the results showed that biomass moisture above 17% yielded less than 50% glucose. Sulfuric acid exhibited the best performance with a glucose yield of 74.5%, and the glucose yield had a direct relationship with the non-carbohydrate components of biomass.

Summary: In this study, different valences of metal chlorides were used as co-catalysts in a Type II deep eutectic solvent (DES) system to enhance the pretreatment of oil palm fronds (OPF). The results showed that using ChCl:CaCl2 center dot 6H(2)O/1 wt% CuCl2/30 vol% water and ChCl:CaCl2 center dot 6H(2)O/1 wt% FeCl3/20 vol% water as pretreatment conditions could achieve high xylose recovery from OPF. Additionally, these co-catalysts were effective in removing lignin, xylan, and arabinan from OPF. Therefore, using DES + co-catalyst system with additional water content can be a promising approach for OPF pretreatment in biorefinery processes.

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.
