1 Scope
This standard specifies the rapid screening of carcinogenic aromatic amines (see Appendix A) in textiles by gas chromatography-mass spectrometry
method.
This standard applies to the printing and dyeing of various textile products.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
GB/T 6682 Analytical laboratory water specifications and test methods
GB/T 17592 Textiles - Determination of banned azo dyes
GB/T 23344 Textiles - Determination of 4 - amino - azobenzene
3 principle
The sample was reconstituted with sodium hydrosulfite in a citrate buffer solution to produce the presence of carcinogenic aromatic amines,
Ethyl ester was extracted and analyzed by gas chromatography-mass spectrometry (GC/MSD). According to the retention time of aromatic amines and mass spectrometry, the internal standard method
Quantitative.
4 reagents and materials
4.1 General rules
Unless otherwise stated, the reagents used in the analysis are both analytical and GB/T 6682 for tertiary water.
4.2 Methanol.
4.3 Ethyl acetate.
4.4 Citrate buffer (0.06 mol/L, pH = 6.0). 12.526 g of citric acid and 6.320 g of sodium hydroxide were added, dissolved in water,
To 1000 mL.
4.5 sodium dithionite solution (200mg/mL). take sodium dithionite (Na2S2O4 content ≥ 85%), dissolved in water, is now with the use.
4.6 anhydrous sodium sulfate.
4.7 Mixed aromatic amine standard stock solution (1000mg/L). with methanol or other suitable solvent preparation.
Note. This solution is stored in a brown bottle, and can be placed in a small amount of anhydrous sodium sulfite, frozen in the refrigerator to save, valid for a month.
4.8 mixed aromatic amine standard working solution (20mg/L). respectively, to absorb aromatic amine standard stock solution (4.7) 0.2mL placed in the same capacity
The flask was fixed to 10 mL with ethyl acetate. Now with the current use.
Note. Other suitable concentrations can be formulated as needed.
