Introduction
Stop using polychlorinated biphenyls (PCB) in 1971 before, PCB as a raw material present in the NCR. Since some paper
These contain carbon, so the recycled pulp with the PCB, may result in contamination of paper and paperboard.
Some PCB pollutants PCB congeners used in earlier NCR, which also can be seen as PCB pollution.
This standard, designated on Seven PCB congeners (PCB18,28,52,101,138,153 and 180) were measured separately. due to
PCB congeners can be considered as PCB sources, the paper can be estimated by the total content of these seven PCB congeners content.

Determination of 7 specified polychlorinated biphenyls
1 Scope
This standard specifies the method for determination of contact with the food pulp, paper and paperboard of seven specified polychlorinated biphenyls (PCBs) in.
This standard applies to the determination of contact with the food pulp, paper and paperboard of seven specified polychlorinated biphenyls (PCBs) in.

Principle 3
Potassium hydroxide ethanol solution to be tested is boiled PCBs extracted from the paper. After the extract was mixed with water, a one-time solution - Solid
Distribution C18 solid phase extraction column, then eluted with n-hexane or iso-octane.
N-hexane phase containing PCBs use with electron capture detector (ECD) or mass selective detector (MSD) of a given capillary gas chromatography
the amount. Each of the seven PCB congeners PCB standard peak shape and peak physiognomy comparison, if the peak shape is consistent, the total content of the PCB by PCB congeners
Content estimates obtained.
4 instruments and equipment
4.1 Examples of extraction apparatus, see Appendix A, which contains a length of about 200mm, an inner diameter of 30mm glass tube. By the end of the glass tube
Gradient fine in order to ensure air-tightness of the disposable SPE column connected at its top and the formation of droplets.
4.2 disposable SPE, C18 bonded phase (size of 3.0mL, 200mg).
4.3 Gas chromatograph. equipped with electron capture detector (ECD) or mass selective detector (MSD).
5 Reagents
Unless otherwise specified, all reagents were of analytical grade, double distilled water or water of equivalent purity.
5.1 Ethanol. purity ≥99.5%.
5.2 methanol. purity ≥99.8%.
5.3 hexane. purity ≥98.0%.
5.4 Concentrated sulfuric acid. a density of about 1.84.
5.5 potassium hydroxide.
5.6 standard sample. purity ≥99.5%.
5.6.1 2,2 ', 5-trichlorobiphenyl (PCB18, BalschmitNomenclature coding).
5.6.2 trichloro biphenyl (PCB28, BalschmitNomenclature coding).
5.6.3 2,2 ', 5,5'-tetrachlorobiphenyl (PCB52, BalschmitNomenclature coding).
