The capability of Rhizobium meliloti on degrading 2,4,4'-trichlorobiphenyl and 18 kinds of polychlorinated biphenyl congener mixtures was studied by shaking flask experiment. The results showed that the degradation capability of Rhizobium meliloti to 2, 4, 4'-trichlorobiphenyl increased gradually with the

Sorption behaviors of PCB28 to phosphatidylcholine (PC)and triglyceride (TG) were studied. Results showed that sorption equilibrium could be achieved in 8 h for PCB28, and the sorption amount on PC was higher than that of TG when the initial PCB28

Dechlorination of polychlorinated biphenyls (PCBs) by nanoscale zerovalent iron (NZVI) is often strongly hindered by increased pH because large amounts of H(+) ions were consumed during the surface reaction. The main objective of this work was to evaluate the effect
