Abstract
为检测纺织品中苯并(a)蒽的分析方法,建立高效液相色谱-荧光检测法(HPLC-FLD),以甲醇为萃取剂,采用Agilent Eclipse SB-C18色谱柱(100.0 mm×4.6 mm,3.5 μm)对超声萃取后的目标物进行分离,以色谱保留时间和光谱图进行定性,外标法定量.在优化试验条件下,苯并(a)蒽在0.5~100.0 μg,/L范围内呈良好线性关系,相关系数大于0.999 0;方法定量限(S/N=10)0.05 mg/kg;添加水平为0.10~1.00mg/kg时,回收率为93.5%~101.2%,相对标准偏差(n=6)为2.7%~3.4%.该方法前处理简便、回收率高、精密度好,能够满足纺织品中苯并(a)蒽的测定.
