Summary: This study proposes a fluidized preoxidation-low-temperature reduction magnetization roasting process for the utilization of low-grade refractory siderite-containing iron ore. Through experiments, it was found that the γ-Fe2O3 generated during air oxidation roasting would further convert into weakly magnetic FeO. Stable magnetite can only be obtained through reduction of γ-Fe2O3 at low temperatures. The optimal process parameters for fluidized magnetization roasting were determined to be preoxidation at 610°C for 2.5 min, followed by reduction at 450°C for 5 min. The iron ore concentrate obtained through weak magnetic separation had a grade of 62.0wt% and an iron recovery rate of 88.36%. Compared to conventional direct reduction magnetization roasting, the weak magnetic separation greatly improved the iron recovery by 34.33%. The proposed roasting process enables efficient utilization of low-grade refractory siderite-containing iron ore without wustite generation, and it is not limited by the proportion of siderite and hematite in the ore.

Summary: The reduction behavior of different size fractions of high-purity hematite was investigated to address the asynchronous reaction issue in heterogeneous and complex refractory iron ore. The results indicated that reducing the ore size promoted the transformation from hematite to magnetite, with the newly formed magnetite exhibiting a loose porous structure. This structure facilitated the contact between CO gas and the new hematite surface. However, an increase in ore particle size increased CO diffusion resistance, resulting in an asynchronous reaction.

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.
