Article Abstract
The extensive applications of decabromodiphenyl ethane (DBDPE), a novel brominated flame retardant, have induced its accumulation in sediment, which may have a great negative impact on the ecological environment. In this work, the biochar/nano-zero-valent iron materials (BC/nZVI) were synthesized to remove DBDPE in the sediment. Batch experiments were carried out to investigate the influencing factors of the removal efficiency, and kinetic model simulation and thermodynamic parameter calculation were performed. The degradation products and mechanisms were probed. The results indicated that the addition of 0.10 g·g BC/nZVI to the sediment with an initial concentration of 10 mg·kg DBDPE could remove 43.73% of DBDPE during 24 h. The water content of the sediment was a critical factor in the removal of DBDPE, which was optimal at 1:2 of sediment to water. The removal efficiency and reaction rate were enhanced by increasing dosage, water content, and reaction temperature or decreasing initial concentration of DBDPE based on the fitting results of the quasi-first-order kinetic model. Additionally, the calculated thermodynamic parameters suggested that the removal process was a spontaneously and reversibly endothermic reaction. The degradation products were further determined by GC-MS, and the mechanisms were presumed that DBDPE was debrominated to produce octabromodiphenyl ethane (octa-BDPE). This study provides a potential remediation method for highly DBDPE-contaminated sediment by using BC/nZVI.

Developing solid electrolytes with high ionic conductivity, a high voltage window, low flammability, and excellent interface compatibilities with both the anode and cathode for lithium-metal batteries is still a great challenge but highly desirable. Herein, we achieve this target through an in situ copolymerization of vinyl ethylene carbonate (VEC) together with acrylonitrile (AN) under fitting ratios inside a porous polyacrylonitrile (PAN) fiber membrane doped with flame-retardant decabromodiphenyl ethane (DBDPE) molecules. The received fiber-reinforced polycarbonate-based composite electrolyte with an ultrathin thickness of 13 μm exhibits good internal interfacial compatibility because of the same AN structure and superior flame-retardant performance due to the doped DBDPE molecules.

Soil serves as the habitat for numerous organisms and is increasingly threatened from co-pollution of novel brominated flame retardant (NBFRs) and heavy metals (HMs). Focusing on Deca-bromodiphenyl ethane (DBDPE) and cadmium (Cd) as the targets, we constructed a soil-lettuce-earthworm microcosm to explore co-pollution effects in rhizosphere soils. Results showed that DBDPE increased bioavailable Cd fraction to amplified its ecological risks.

Lithium metal batteries (LMBs) are expected to increase energy density due to the high capacity and low electrode potential of lithium metal. However, lithium dendrite growth and organic liquid electrolytes exacerbate the risk of thermal runaway. To improve the safety of the battery, a multifunctional flame-retardant separator was developed through the synergistic effect of decabromodiphenyl ethane (DBDPE)/AlO nanoparticle composite modification.

The uptake of microplastics (MPs) by terrestrial invertebrates poses potential threats to soil ecosystems. This study investigated the uptake of polypropylene MPs in Eisenia fetida, focusing on two exposure routes (gut and skin) and key influencing factors (particle size and concentration). A 50-day uptake-elimination experiment was conducted using four MP concentrations (0.

Decabromodiphenyl ethane (DBDPE) is widely used as an additive flame retardant and has led to global pollution. Its has a large molecular mass and is prone to debromination and degradation under photothermal conditions, resulting in smaller homologous compounds. Due to the lack of standard substances for debromination products, the in-depth study of DBDPE environmental geochemical behavior through debromination conversion has been hindered.
