摘    要:建立高效液相色谱紫外检测的分析方法,同时测定涤纶缝纫线中分散黄1、分散黄3、分散黄9、分散黄49、分散红1、分散红11、分散红17这7种致敏性分散染料。样品经甲醇超声提取后,采用C18色谱柱,以乙腈(内含0.1%甲酸)和0.02 mol/L乙酸铵(内含0.1%甲酸)为流动相,梯度洗脱分离,在360、440、480 nm波长下进行检测。7种分散染料的加标回收率在90.0%~101.0%之间,其相对标准偏差在1.0%~5.4%之间,待测化合物在1.0~50.0 mg/L之间均具有良好的线性,回归系数均大于0.999,检出限(LOD)在0.2~1.0 mg/kg之间。本方法简便、灵敏、重现性好,能满足涤纶缝纫线中分散染料的监测要求。

关 键 词:高效液相色谱法  涤纶缝纫线  致敏性分散染料  紫外检测

Abstract:A method for simultaneous determination of seven allergenous disperse dyestuffs,such as Disperse Yellow 1,Disperse Yellow 3,Disperse Yellow 9,Disperse Yellow 49,Disperse Red 1,Disperse Red 11 and Disperse Red 17 in polyester sewing thread by high-performance liquid chromatography-ultraviolet detection is introduced.After the sample is extracted by ultrasonic technology with methanol,the extract is separated on a C18 column by gradient elution with acetonitrile(containing formic acid 0.1%)/ 0.02 mol/L ammonium acetate(containing formic acid 0.1% as the mobile phase.Detection is carried out by ultraviolet detector at 360 nm,440 nm and 480 nm.The extraction recoveries of the seven dyestuffs are at 90.0%~101.0%,with RSDs at 1.0%~ 5.4%.The compounds to be tested have good linearity within the range of 1.0~50.0 mg/L,and regression coefficient is more than 0.999.The limits of detection(LOD) are at 0.2~1.0 mg/kg.This established method is simple and sensitive,has good reproducibility,and can satisfy the monitoring of the seven allergenous disperse dyestuffs in polyester sewing thread.
Keywords:liquid chromatography  polyester sewing thread  allergenous disperse dyestuffs  ultravtolet detection
