Summary: Iron-modified biochar (Fe-BC) prepared in this study showed enhanced adsorption capability for copper and sulfadiazine compared to pristine biochar (BC). The iron modification enlarged the surface area and loaded iron oxide nanoparticles on biochar surface, improving the adsorption efficiency. In the binary-pollutants system, there was a synergistic effect on the adsorption of Cu2+ and SDZ, possibly due to mutual bridging effects and complexation between the two pollutants. Fe-BC700 exhibited better removal efficiency for Cu2+ and SDZ in the binary system compared to single systems.

Summary: Magnetized activated carbons (MAC) prepared from rape straw powder showed high adsorption capacities for Pb(II) and Cd(II) due to surface active points, with adsorption behavior conforming to the Freundlich model and pseudo-second-order kinetic model. Thermodynamic parameters indicated spontaneous and endothermic reactions. Adjusting the pH of the solution could enhance adsorption capacity, but competitive adsorption occurred in the presence of high-valent ions. Adsorption mechanisms included electrostatic attraction, surface complexation, and co-precipitation. The MAC material showed potential for heavy metal ion removal from aqueous solutions.

Summary: Rapid industrialization is a major cause of global land degradation and environmental problems, particularly due to coal-burning power stations releasing pollutants. This study evaluates the use of bamboo plantations, facilitated by organic amendments, for the bioremediation/phytoremediation of fly ash-degraded land. Results show that after two years of plantation, all physicochemical attributes of the degraded land improved considerably. Different bamboo species demonstrated varying phytoremediation mechanisms, with B. balcooa being the most effective for certain pollutants. Overall, bamboo plantations contributed to environmental restoration and carbon sequestration, making them a recommended solution for land degradation.

Summary: The content of Zn in soil and the use of organic fertilizers can affect the uptake of micronutrients by plants. A pot experiment was conducted to investigate the impact of different Zn application rates and organic fertilization on the Cu and Ni content, uptake, and bioaccumulation factor in cocksfoot. The results showed that higher Zn application rates significantly decreased the content, uptake, and bioaccumulation factor of Cu in the grass. Conversely, the application of Zn did not affect the content and bioaccumulation factor of Ni, except for a slight increase in Ni uptake at a lower Zn application rate. The use of organic fertilizers increased the content, bioaccumulation factor, and uptake of Cu and Ni in cocksfoot.

Summary: Microwave biochar produced with activated carbon catalyst shows excellent potential in removing heavy metals from waste water due to its high specific surface area and adsorption capacity. The optimum pH value for heavy metal removal is between 5-6, and Pb2+ exhibits the strongest affinity. The adsorption process is mainly explained by monolayer adsorption and chemical adsorption mechanisms. Complexation with oxygen-containing functional groups and precipitation with carbonate are the predominant adsorption mechanisms.

Summary: This study systematically investigated the degradation performance and mechanism of chloramphenicol (CAP) using UV/sulfite advanced reduction processes (ARPs). The results showed that UV/sulfite-ARPs achieved simultaneous degradation efficiency of 90.67% and dechlorination efficiency of 92.22% within 50 minutes. The study also found that the degradation and dechlorination of CAP were influenced by sulfite concentration, and complete degradation and dechlorination were achieved. The presence of co-existing anions and water matrices had negligible effect on the degradation and dechlorination efficiencies of CAP.

Summary: Perfluorobutane sulfonate (PFBS) is a potential replacement for perfluorooctane sulfonates (PFOS), but it has also been found to be hazardous. The UV/S (IV) system effectively removes PFOS from water but is inefficient for PFBS decomposition. A hybrid vacuum-ultraviolet (VUV)/S (IV)/KI process was investigated and found to significantly enhance the degradation of PFBS in aqueous solution. The presence of KI and alkaline conditions improved the degradation efficiency, while various ions such as Cl-, HCO3-, NO3-, NO2-, and HA inhibited the process.

Summary: The composition variation, spatiotemporal succession, and assembly processes of bacterial generalists and specialists in the plastisphere were investigated. Colonization time mainly mediated the composition variation, and richness differences also affected the composition variation of generalists and specialists. Deterministic processes dominated the assembly of generalists, while stochastic processes dominated the assembly of specialists. The community stability of generalists on non-biodegradable and biodegradable microplastics was lower than corresponding specialists.

Summary: A novel approach using ball milling and oxalic acid to modify sludge-based biochar was found to enhance its activation performance for degrading sulfamethoxazole. The system showed high removal rates for sulfamethoxazole at different pH levels and had good tolerance to background electrolytes. Non-radicals and surface-bound radicals were identified as the main contributors to the degradation process. The transformed products generated in the system were less toxic than sulfamethoxazole. After multiple reuse cycles, the system maintained a high removal rate. This study provides valuable insights for the treatment of municipal sludge.
