建立了皮革中致敏性分散染料的检测方法。采用超声波辅助甲醇对样品进行萃取,萃取温度70℃、时间30min,萃取液经聚四氟乙烯滤膜过滤后,用高效液相色谱-二极管阵列检测器法(HPLC-DAD)进行测定。当标样的浓度为0.5~10mg/L时,线性相关系数≥0.999,检出限5.0mg/kg,空白样品的加标回收率为≥60%。 Established a sensitized leather in the detection of disperse dyes. The sample was extracted with ultrasonic-assisted methanol. The extraction temperature was 70 ℃ and the time was 30 min. The extract was filtered through a Teflon filter and determined by high performance liquid chromatography-diode array detector (HPLC-DAD). When the concentration of standard sample was 0.5-10 mg / L, the linear correlation coefficient was ≥0.999, the detection limit was 5.0 mg / kg, and the spiked recoveries of blank samples were ≥60%.
