摘　　要：建立了纺织品中苯并三唑类紫外吸收剂的高效液相色谱(HPLC)分析检测方法。通过对纺织品中苯并三唑类紫外吸收剂2-(2′-羟基-3′,5′-二叔戊基苯基)苯并三唑(UV-328)和2-(2′-羟基-3′-异丁基-5′-叔丁基苯基)苯并三唑(UV-350)的测定,结果表明在一定浓度范围内线性关系良好,相关系数(R^(2))均大于0.999,方法简单快速,回收率和精密度良好,具有较好的灵敏度,适用于纺织品中紫外吸收剂的检测方法。A high performance liquid chromatography(HPLC)method was developed for the determination of benzotriazoles in textiles.2-(2′-hydroxy-3′,5′-di-tert-pentylphenyl)benzotriazole(UV-328)and 2-(2′-hydroxy-3′-isobutyl-5′-tert-butyl phenyl)benzotriazole(UV-350)in textiles was determined.The results showed that the linear relationship was good in a certain range of concentration,the correlation coefficient(R 2)was higher than that of 0.999.The method was simple and rapid,the recovery and precision were good,and the sensitivity was good,suitable for the Quantitative analysis of such UV absorbers in textiles.
