高效液相色谱法测定纺织品中喹啉的质量浓度

建立了测定纺织品中喹啉质量浓度的高效液相色谱检测方法,用高效液相色谱仪对样品中的喹啉及其他组分进行分离,用二极管阵列检测器进行紫外光谱分析,用峰面积外标法进行定量。喹啉的检出限为10 mg/kg,回收率在80%~120%,精密度小于2%。结果表明,该方法线性良好,测试简单,回收率、精密度高,满足测试要求。

Determination of quinoline mass concentration in textiles by high performance liquid chromatography

The high performance liquid chromatography for the determination of quinoline mass concentration in textiles was established.The quinoline and other components in the sample were separated by high performance liquid chromatography.The ultraviolet spectrum was analyzed by a diode array detector.The external method of peak area for quantitative analysis was used.The detection limit of quinoline is 10 mg/kg,the recovery rate is between 80% and 120%,and the precision is less than 2%.The results show that the method has good linearity,simple test,good recovery and precision,and meets the test requirements.
