Efficient Adsorption Removal of Tetrabromobisphenol A from Water by Using a Magnetic Composite Fe3O4/GO/ZIF-67
AI summary Read the abstract
Researchers synthesized a magnetic composite material (Fe3O4/GO/ZIF-67) and demonstrated its highly efficient adsorption of tetrabromobisphenol A (TBBPA), a widely used brominated flame retardant, achieving a removal capacity of 232 mg/g within 120 minutes. The adsorption mechanism was driven by hydrogen bonding and pi-pi stacking interactions, and the magnetic properties allow easy recovery of the adsorbent from water.
Tetrabromobisphenol A (TBBPA) is a kind of widely used brominated flame retardant (BFR), which is proven to be harmful to ecological systems and public health. It is very important to remove TBBPA from the environment. In our study, a magnetic composite named Fe3O4/GO/ZIF-67 was synthesized by a coprecipitation method and applied in the highly efficient adsorption of TBBPA from water. Static adsorption experiments demonstrated that the adsorption capacity could reach 232 mg·g−1 within 120 min, which is much higher than those reported in the other literature. The experimental results show that the adsorption of TBBPA on Fe3O4/GO/ZIF-67 followed Langmuir and pseudo-second-order kinetic adsorption models. The main mechanisms for these adsorptions were identified as hydrogen bonds between OH groups in TBBPA and COOHs of Fe3O4/GO/ZIF-67, and π-π stacking between Fe3O4/GO/ZIF-67 and TBBPA. This study provides a method with great promise for the design and synthesis of better adsorbents for the removal of TBBPA from the water environment.

AI summary Read the abstract
The sorption of the flame retardant tetrabromobisphenol-A (TBBPA) onto four types of microplastics — polyethylene, polypropylene, polystyrene, and polyvinyl chloride — was studied in aqueous environments. Results revealed that polymer type, surface area, and hydrophobic interactions were key factors controlling how much TBBPA accumulates on microplastic surfaces.

Association of tetrabromobisphenol A (TBBPA) with micro/nano-plastics: A review of recent findings on ecotoxicological and health impacts
AI summary Read the abstract
This review examines how tetrabromobisphenol A (TBBPA), a widely used flame retardant found in plastic products, binds to micro and nanoplastics in the environment. When TBBPA hitches a ride on microplastics, the combined effect on organisms and ecosystems is often worse than either contaminant alone. Since TBBPA is an additive in many plastic products, the findings highlight how microplastics can carry harmful chemicals directly into the body.
