The effect of copper ions on the water solubility enhancement of 4,4'- dibromodiphenyl ethers (BDE-15) by a commercial humic acid (HA) has been studied using batch equilibrium technique at various pHs. The characteristics of HA-Cu complex were investigated with the

The anaerobic microbial and photochemical degradation pathways of 4,4'-dibromodiphenyl ether (BDE15) were examined. BDE15 was reductively debrominated within a fixed-film plug-flow biological reactor at hydraulic retention times of 3.4 and 6.8 h, leading to exclusive production of 4-bromodiphenyl ether (BDE3)

In situ transformation of 4,4'-Dibromobiphenyl (4,4'-DBB) in water was observed with hydrothermal diamond anvil cell (HDAC) up to 633 K. It shows that 4,4'-DBB dissolves in water to form a homogenous phase at the temperature of 588 K and thus
