1 Scope

This standard specifies three (2,3-dibromopropyl)phosphate, polybrominated biphenyl, pentabromodiphenyl ether and octabromodiphenyl ether in textiles. Detection method. This standard applies to the flame retardant finishing agent tris(2,3-dibromopropyl)phosphate, polybrominated biphenyl, pentabromodiphenyl ether and octabromodiphenyl ether in textiles. Determination.

2 Terms and definitions

The following terms and definitions apply to this standard. Add substances that prevent flame burning in textiles. Such as. Tris (2,3-dibromopropyl) phosphate (Tris (2,3-dibromopropyl) Phosphate), polybrominated biphenyls (PBBs), pentabrominated diphenyl Ether) and octabrominated diphenylether.

3 Principle

The sample was extracted by Soxhlet using toluene as the extraction solvent, and the extract was concentrated and chromatographed by gas chromatography-mass spectrometry. analysis.
