Fibreboard and chipboard phthalates
Determination of content
1 Scope
This standard specifies the fiberboard and particleboard phthalate content of gas chromatography/mass spectrometry - selected ion monitoring (GC/MS-
SIM) method of determination.
This standard applies to fiberboard and particleboard dibutyl phthalate (DBP), butyl benzyl phthalate (BBP), o-benzene two
(2-ethylhexyl) formate (DEHP), di-n-octyl phthalate (DNOP), diisodecyl phthalate (DIDP)
Determination of acid diisononyl ester (DINP) content.
2 principle
The n-hexane was used to extract the phthalate in the sample by ultrasonic extraction. The extract was determined by gas chromatography/mass spectrometry
And confirmed that the external standard method.
3 Reagents and materials
3.1 n-hexane, chromatographic purity.
3.2 Phthalate standards. DBP, BBP, DEHP, DNOP, DIDP and DINP, purity ≥97%, see Appendix A.
3.3 Standard stock solution Accurately weighed amount of phthalate standard (3.2), with n-hexane (3.1) formulated DBP, BBP,
DEHP, DNOP concentration of 2g/L standard stock solution, DIDP, DINP concentration of 20g/L standard stock solution.
3.4 Standard Working Solution The DBP, BBP, DEHP and DNOP concentrations of 0.5mg/L ~ 10mg/L,
DIDP, DINP concentration from 5mg/L ~ 100mg/L between the one or several mixed standard working solution.
Note. The standard solution is protected from light at below 4 ℃. The standard stock solution is valid for 6 months. The standard working solution is valid for 3 months.
