皮革中富马酸二甲酯的快速测定

The Determination of Dimethylfumarate' Contents Which in Leather

建立并验证了用HPLC-UV测定皮革中富马酸二甲酯的检测方法,主要以乙腈为提取溶剂,采用超声波提取法提取皮革中富马酸二甲酯,以相对保留时间定性,色谱峰面积定量;实验结果表明,乙腈平均回收率为94.31%～100.83%,RSD为0.993%～1.468%;检测限(S/N=3)为0.12mg/kg,乙腈提取皮革中富马酸二甲酯的方法操作简单,结果准确.

Established and tested the dimethylfumarate（DMF） which in leather using HPLC-UV, using acetonitrile as solvent, adopting supersonic wave extracted the DMF from the leather, qualitative with relatively retention time and quantitative with peak area. The average recovery rate is 94.31%-100.83%, RSD is 0.993%-1.468%, and the detection limit （S/N=3） is 0.012mg/kg. The experiment shows that this method which using acetonitrile as solvent to extract the DMF from the leather is simple and accurate.
