Abstract: The 0.5 mg of suspected solid waste sample of imported textile raw materials was taken, and desorption was conducted at an interface temperature of 310 ℃, a thermal desorption temperature of 310 ℃, and a thermal desorption time of 0.3 min. The 32 hazardous substances of four types including light stabilizers, antioxidants, phthalate plasticizers, and adipate plasticizers were separated on a J&W HP-5MS UI chromatographic column using a temperature program, ionized by electron impact ionization source, and quantified in selected ion monitoring mode. It was shown that linear relationships between values of the masses of the 32 hazardous substances and peak areas of the quantitative ions were kept in definite ranges, with detection limits (3S/N) in the range of 0.5-3.0 mg·kg⁻¹. A blank commercial cotton was used as the matrix for spiked recovery tests at three concentration levels, giving recoveries in the range of 80.2%-97.3%, and RSDs (n=6) of the determined values ranged from 3.1% to 15%. The proposed method was applied to the analysis of 22 suspected solid waste samples of imported textile raw materials, and 2,4-di-tert-butylphenol or di-(2-ethylhexyl) phthalate was detected in 16 samples, with detection amounts in the ranges of 9.3-135.7 mg·kg⁻¹ and 3.0-296.4 mg·kg⁻¹, respectively.
