AN EFFICIENT AND GREEN CLEANUP SYSTEM FOR ANALYSIS OF DIOXIN/FURANS, DIOXIN-LIKE PCBS AND PBDES
We have used a fast and relatively cost effective method, the CAPE Technologies coupled carbon-acid silica column, to improve the efficiency for the analysis of PCDD/Fs, dioxin-like PCBs and PBDEs in environmental samples. Blank concentrations for total 24 PBDEs (3-Br to 10-Br) ranged from 0.483 to 1.39 ng/column and the main congeners detected were BDE-47, BDE-209 and BDE-99. The MDL for total PBDEs using the new cleanup process was determined to be 4.47 ng/g. Since 2008 we have tested 64 real samples of different environmental matrices using this method. The recovery range was 65.7％～103％ for 13C12-PCDD/Fs, 52.2～81.8％ for 13C12-PCBs, and 36.7％～106％ for 13C12-PBDEs. These results meet the QA/QC criteria of US EPA Methods 1613B, 1668A and 1614. We have successfully applied this technique to biological samples, sediments, and dustfall samples, and are now extending its application to other sample matrices.
