摘要
建立了液相色谱-串联质谱对纺织品中苯并三唑类紫外线吸收剂UV-327和UV-328的测定方法。采用反相C18色谱柱，乙腈-0．1％甲酸溶液为流动相，以0.3mL／min流速进行梯度洗脱。采用电喷雾离子源（ESI），多反应监测模式检测。结果表明，UV-327和UV-328在0．01～50μg／mL范围内，峰面积A与浓度C呈良好的线性关系，检出限分别为0．015μg／mL和0．011μg／mL，加标回收率为99．2％。该方法灵敏度高、操作简便，可测定纺织品中苯并三唑类紫外线吸收剂UV-327和UV-328。
A new method for determination of 2-（2＇-hydroxy-3＇, 5＇-di-tert-butylphenyl）-5-chtorobenzotri- azole （UV-327） and 2-（2-hydroxy-3,5-di-tert-amylphenyl） benzotriazole （UV-328） in textiles is developed by HPLC-MS/MS. The analysis is performed on a C,8 column, gradient eluted by CH3CN-H20 （containing 0.1% formic acid）, in the speed of 0.3 mL/min. Electrospray ionization （ESI） and multiple reaction monitoring are used for mass spectrometry analysis. The results show that the good linear relationship be- tween the peak area and the concentration exists over the range of 0.01-50 μg/mL for UV-327 and UV- 3：28. The detection limits are 0.015 μg/mL and 0.011μg/mL, the average recovery is 99.2%. The method is proved to be sensitive and simple, and can meet the testing demands of ultraviolet absorbers UV-327 and UV-328 in textiles.
