摘要
通过萃取和优化仪器条件，建立了高效液相色谱-串联质谱法（HPLC-MS/MS）测定纺织品中2-（2’-羟基-5’-甲基苯基）．苯并三唑的含量，并分析该物质的质谱图和母离子可能的裂解机理。该方法采用Yafian Pumuit？XRs C18色谱柱，含0．1％甲酸的CH3CN-H2O溶液（65：35）作为流动相，并以多反应监测模式进行定性定量分析。结果表明，在0．01-50．00mg/L范围内，UV-P峰面积S与浓度C呈良好的线性关系，回归方程为s=1．0×10^7C＋2．0×10^6，相关系数为0．9998；以3盯计算得UV-P的检出限为3ng/L，平均回收率为96．4％～102．6％。该方法灵敏度高、操作简便，可用于纺织品中苯并三唑类紫外线吸收剂中UV-P的日常检测。
A novel HPLC-MS/MS method for determination of 2- （2＇-hydroxy-5＇-methyl-phenyl} -benzotriazole （ such as comme- rial product UV-P） in textiles is developed by improving extraction and HPLC-MS/MS conditions. Mass spectra of UV-P and the possible fragments of parent ion are also analyzed. The analysis is performed on a Varian Pursuit ？ XRs C18 column with CH3CN-H20（containing 0.1% formic acid） as mobile phase, and by multiple reaction monitoring （MRM） as analysis mode. The results show that, the good linearity exists over the range of 0.01-50.00 mg/L for UV-P. The regression equation and correla- tion coefficients are S= 1.0x10^7C＋2.0xl0^6,r=0.999 8 respectively. The detection limit is 3 ng/L（3~） and the average recovery is from 96.4% to 102.6%. The method is proved to be sensitive, simple, and can meet the requirements of the determination of 2- （2＇-hydroxy-5＇-methyl-phenyl）-benzotriazole in textiles.
