高效液相色谱法测定有机硅涂料中多环芳烃
Keywords: 高效液相色谱,多环芳烃,有机硅涂料
Abstract:
？建立了一种采用高效液相色谱检测有机硅涂料中多环芳烃的方法，该方法所用色谱柱为多聚c18(lc-pah)柱，流动相为乙腈/水，采用梯度淋洗方式，开始时为40%乙腈，28min后变为82%乙腈，48min后变成100%乙腈，保持8min。该方法的线性范围为0.10～200mg/l，线性相关系数为0.9993～1.0000，平均回收率为69.59%～100.31%，精密度实验rsd为1.34%～7.84%，检测限(s/n=5)为0.05～0.10mg/l。该方法完全可以满足有机硅涂料中多环芳烃的检测要求。
