摘要:
建立一个气相色谱-质谱联用方法，可同时测定纺织品中7种苯并三唑类紫外线吸收剂的含量．是以二氯甲烷为萃取溶剂，60 ℃下微波萃取纺织品中的苯并三唑类紫外线吸收剂，萃取液经浓缩定容后进行气相色谱-串联质谱分析，外标法定量．在信噪比为10的条件下，UV-320和UV-328的定量下限均为1.0 μg/kg，UV-P、UV-326、UV-327、UV-329和UV-350的定量下限均为0.5 μg/kg．在3个不同加标质量浓度下，各组分的加标平均回收率为82.69%~93.24%，相对标准偏差为3.12%~6.99%．该方法简单快速、定性可靠、定量准确、灵敏度高、定量下限低，可满足纺织品中苯并三唑类紫外线吸收剂含量检测的需要．采用该方法对市售纺织品中苯并三唑类紫外线吸收剂含量进行测定，结果在1个样品中检出UV-327．
Abstract:
This paper establishes an effective gas chromatography-tandem mass spectrometric (GC-MS-MS) method to determine the contents of seven benzotriazole ultraviolet absorbers in textiles simultaneously. Benzotriazole ultraviolet absorbers in textiles were first extracted at 60 ℃ by using dichloromethane as the extraction solvent with the assistance of microwaves. The extract was then condensed and analyzed by GC-MS-MS and calibrated by the external standard method. At the signal to noise ratio (S/N) of 10, the limit of quantification (LOQ) was 1.0 μg/kg for UV-320, and UV-328, and 0.5 μg/kg for UV-P, UV-326, UV-327, UV-329 and UV-350, respectively. The average recoveries changed from 82.69% to 93.24% under three different spiked levels, while the relative standard deviation (RSD) varied from 3.12% to 6.99%. The proposed method is simple, rapid, accurate and sensitive, and it could satisfy completely the technical demand for the determination of benzotriazole ultraviolet absorbers in textiles. The proposed method has been used to determine the contents of benzotriazole ultraviolet absorbers in commercially available textiles, and we have detected UV-327 in one sample.
