Область применения
This standard specifies the permissible limits and determination methods for 23 harmful aromatic amines in dye products. It is applicable to commercial dyes, dye products, dye intermediates, and textile dyeing auxiliaries of various forms. Manufacturers must ensure their dye products comply with these strict limits to enter the Chinese market. It references GB/T 6682-2008 for laboratory water specifications.
Технические требования
The standard establishes a mandatory limit for harmful aromatic amines in dye products. The content of each specified harmful aromatic amine must not exceed 150 mg/kg. For liquid dyes and pigment pastes, this limit must be calculated based on their solid content. All listed aromatic amines, including benzidine and 2-naphthylamine, are strictly regulated under this threshold. The standard replaced the previous GB 19601-2004, updating the quantitative method to an internal standard method and removing the gas chromatography analysis method.
Методы испытаний
The testing procedure involves reducing the dye sample in a citrate buffer solution (pH=6.0) using sodium dithionite. The cleaved solution is then extracted with an organic solvent, concentrated, and analyzed using Gas Chromatography-Mass Spectrometry (GC/MS). Quantification is performed using the internal standard method to ensure high accuracy. The minimum quantitative limit of this method is 20 mg/kg, with recovery rates required to be between 70% and 130%.
