Summary: The production of herbal medicine residues has increased rapidly, leading to the exploration of potential raw materials for biochar preparation. In this study, iron-loading biochar (Fe-BC) was prepared from Chaga mushroom residues using a carbothermic reduction method. Fe-BC was found to be an effective adsorbent and catalyst for removing tetracycline (TC) from water. Various factors, such as initial concentration, temperature, pH, ionic strength, and water source, were investigated in the TC adsorption process. The results indicated that Fe-BC exhibited a high adsorption capacity for TC, and the addition of hydrogen peroxide (H2O2) further enhanced TC removal.

Summary: The precursor gel was prepared using a sol-gel method, and ultrafine TiN was obtained by Fe-catalyzed carbon thermal reduction nitridation reaction. The addition of Fe significantly promoted the reaction, resulting in ultra-fine TiN nanoparticles with an average size of about 24 nm. The promotion effect of Fe is due to its role in providing nucleation sites for amorphous titanium oxide and facilitating the dissociation of N2.

Summary: The reduction of U(VI) to less soluble U(IV) species on mineral surfaces is a promising approach for remediating uranium contamination. Fe(II) is found to play a more reactive role than humic acid (HA) in this reduction process, and the extent of U(VI) reduction is determined by the Fe(II) content (n). When both HA and Fe(II) are present, two distinct mechanisms are observed: spectator mode, where only one acts as a reducing agent, and combined action mode, where both contribute to the reduction process.

Summary: In this study, the sorption speciation of U(VI) at the phlogopite/water interface was investigated using batch sorption experiments, time-resolved luminescence spectroscopy, and theoretical calculation. The results showed that pH strongly influenced the sorption of U(VI) on phlogopite, while ionic strength had a weak effect. Multiple inner-sphere surface species were formed at the interface, and their abundances varied with pH. The formation of uranyl oxyhydroxides was observed at high pH. Density functional theory calculation indicated that a bidentate complex was the most favorable sorption configuration for U(VI) at acidic condition. The temperature had an enhancing effect on U(VI) sorption, but this effect was reversible.

Summary: Selenium is highly toxic in excess for both animals and humans. Its mobility in the natural oxic environment is generally not an issue due to adsorption with ferric minerals. However, the removal and immobilization of the long-lived radioactive isotope Se-79 from contaminated anoxic waters is currently a significant concern.

Summary: Ultrafine Mo (W) powders were obtained through a two-stage reduction process, including carbo-thermal pre-reduction of MoO3 (WO3) and deep hydrogen reduction. The increase in reaction time reduced the residual carbon contents of pre-reduced products without significantly affecting the particle sizes. After deep hydrogen reduction, the residual carbon contents of the obtained powders were further reduced.

Summary: A new artificial mineralization process was proposed to immobilize uranium (U(VI)) for wastewater decontamination by converting U(VI) pollution into natural minerals. The U(VI) removal efficiency reached up to 96% in the three designed systems at pH 5.0. The precipitation of Mg2+, PO43-, and UO22+ into saleeite (Mg(UO2)(PO4)2·10H2O) crystal contributed to UO22+ immobilization in the systems, resulting in negligible U desorption. The understanding of U(VI) immobilization effectiveness and artificial mineralization mechanism provides a promising strategy for U(VI) decontamination in wastewater.

Summary: The catalytic ozonation of porous carbonaceous materials holds great potential for the treatment of refractory organic contaminants. However, the formation mechanism of hydroxyl radicals and the contribution of reactive oxygen species (ROS) remains contentious. This study used highly porous biochar (HPB700) as a model material and investigated the formation, evolution, and contribution of ROS during catalytic ozonation. The results showed that free hydroxyl radicals were generated during the process, and hydrogen peroxide played a key role in their formation. The findings enhance our understanding of hydroxyl radical formation and the role of different ROS in pollutant degradation.
