Evaluation of Uncertainty of Determination of PBBs and PBDEs in Printed Wiring Boards By GC/MS;

The determination of polybromobiphenyls(PBBs) and polybromobiphenyl ethers(PBDEs) in electrical and electronic equipment were based on gas chromatography–mass spectrum with select ion scan(GC-MS-SIS).

A static solid-phase microextraction procedure combined with liquid-liquid extraction was developed to determine the poly(dimethyl) siloxane(PDMS)-water partition coefficients(Kf) of polybrominated biphenyls(PBBs) by GC-MS.

In order to establish a new method for the PBBs detection by immuno-PCR, two sorts polybrominated biphenyls hapten was synthesized by introducing amino group and carboxyl group as a substituent at the aromatic ring while retaining the biphenyls ring.

A method of simultaneous determination of the eight polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) in textiles by gas chromatography with electron capture detector has been developed.

Immunological assay of polybrominated biphenyl Ⅰ——synthesis and characterization of hapten;

Photodegradation kinetics and pathway of polybrominated biphenyl congener under UV irradiation;

Infra-red spectra of polybrominated biphenyls (PBB) and polybrominated biphenyl ether (PBDE) in electronic and electrical appliances were compared with their standard ones to determine if C-Br bond belongs to the characteristic absorption spectra of 650-500 cm ,thus selecting brominate based flame retardants qualitatively.
