摘要 为了测定纺织品中的苯并三唑类紫外稳定剂,采用超声辅助萃取-气相色谱-串联质谱(USAE—GC—MS/MS)同时测定纺织品中UV-320、UV-350、UV-328和UV-327共4种苯并三唑类紫外稳定剂(BUVSs)。试验结果表明,4种BUVSs线性相关系数(R。)均大于0.999,以信噪比(s/N)为3计算UV-320、UV一350、UV-328和UV-327检出限(己0D)分别为0.009、0.018、0.009和0.018mg/kg,以信噪比(S/N)为10计算定量限(LOQ)分别为0.03、0.06、0.03和0.06mg/kg。在低、中、高3个加标浓度水平下回收率范围为80.2%~116.4%,相对标准偏差(尺5D)为0.1%~9.7%。试验结果表明,该方法可用于分析测定纺织品中苯并三唑类紫外稳定剂。
