Summary: Migrating electric field-assisted electrocoagulation (MEAEC) is a three-electrode electrochemical system that utilizes waste flour-derived sponge biochar (SBC) as an adsorption electrode for efficient phosphorus removal from wastewater. The SBC electrode, with its low energy consumption and excellent effluent quality, demonstrated great potential in phosphate removal. The MEAEC system with SBC electrode achieved a high level of phosphate removal with much lower energy consumption compared to previous studies.

Summary: This study investigated the removal of polyamide microplastics from wastewater using electrocoagulation. The combination of iron anode and aluminum cathode (Fe-Al) exhibited the highest removal efficiency. The removal efficiency of microplastics increased with higher applied voltage and electrolyte concentration. The optimized conditions for polyamide removal were using Fe-Al electrodes, with a plate spacing of 2.5 cm, an applied voltage of 10 V, an initial pH of 7, and an electrolyte concentration of 0.02 mol/L. This study highlights the potential of electrocoagulation for microplastics removal and provides insights for operational parameter optimization.

Summary: Excessive discharge of phosphorus can cause eutrophication, harming public health, the environment, and the economy. Conventional phosphorus removal methods are not suitable for small rural sewage due to their unique characteristics. This study evaluated the use of electrocoagulation with industrial steel electrodes for small rural sewage treatment. The results showed that the best performance was achieved under specific conditions, with a high phosphorus removal efficiency and low energy consumption.

Summary: In this study, electrocoagulation (EC) with composite scrap iron and manganese filings as an anode (Fe-Mn EC) was investigated for the efficient removal of pentavalent antimony (Sb(V)). The results showed that Fe-Mn EC enhanced the removal of Sb(V) by 11.18-17.36% compared to traditional iron electrocoagulation (Fe EC). The removal rate of Sb(V) increased with the current concentration and Mn content in the anode, but was inhibited when the Mn content exceeded 20%. Analysis of the flocs generated during Fe and Fe-Mn EC revealed that the Fe-Mn flocs had a higher Sb(V) adsorption rate and capacity compared to Fe flocs, with a structure of nanometer flakes and large internal surface areas. Thermodynamics constants indicated that adsorption was associated with monolayer physical adsorption. This study provides a new idea and potential technical support for the removal of Sb(V) by introducing composite scrap iron-manganese as an anode in electrocoagulation.

Summary: This study investigated the removal performance, mechanism, and influencing factors of microplastics in wastewater treatment by electrocoagulation (EC). It was found that aluminum anode EC is an effective method to remove microplastics with a removal rate above 80%. The efficiency of microplastic removal by EC is influenced by electrolyte concentration and applied voltage density, with flocculation and charge neutralization occurring simultaneously during the process.

Summary: The electrocoagulation technology is efficient for the removal of phosphate, especially in the secondary effluent containing moderate amounts of Ca2+ and Mg2+. The addition of Ca2+ and Mg2+ under normal and low dissolved oxygen conditions promotes the removal of phosphate by Fe(0) electrocoagulation and enhances the aggregation stability of flocs.

Summary: In this study, a novel method using yellow phosphorus and phosphate rock slurry as absorbent is proposed for purifying H2S, which can achieve high removal efficiency and promote the production of phosphorus chemical products. The method involves H2S oxidation to SO2 and subsequent reaction with phosphate rock to form H2SO4, with the help of active substances generated in the process. High H2S removal efficiency of up to 85% can be achieved even under acidic conditions and low temperatures.

Summary: This study characterizes the biosynthetic logic of Piscibactins and photoxenobactins, metallophores and virulence factors. It shows that the biosynthesis involves heterocyclization domains with different catalytic efficiencies and putative bond cleavage off-loading manners. Spontaneous conversions of the biosynthetic end product also contribute to the production of other products.

Summary: Three unusual sesterterpenoids with novel rearranged colquhounane and tetranorcolquhounane frameworks were isolated from Colquhounia coccinea var. mollis, a medicinal plant from the Lamiaceae family. The structures of these compounds were determined through spectroscopic analysis and quantum chemical calculations. A biomimetic regioselective cyclopropane cleavage reaction was successfully achieved under acidic conditions. Additionally, the immunosuppressive activities of these new sesterterpenoids were evaluated.
