建立了皮革中防腐剂IPBC的检测方法。通过试验各主要技术参数确定为：石油醚作为提取溶剂，在35℃的条件下，用超声提取的方式，对阳性样品进行萃取的效果最好。在80℃保持1 min，以10℃/min的速率升至110℃，保持1 min，以20℃/min的速率升至220℃，保持1 min，后运行280℃，保持5 min的升温程序下，碘代丙炔基氨基甲酸丁酯（IPBC）能得到较好响应时间及面积。当标样的质量浓度为0.5~2.0 mg/L时，线性相关系数≥0.999，检出限为1.0 mg/kg，空白样品的加标回收率为≥60%。

The detection method of preservative IPBC in leather was established. In this paper, it is proved that the effect of ex-tracting positive samples is optimal under the main technical parameters, i.e. petroleum ether as the extraction solvent, tempera-ture 35℃, with ultrasonic extraction. Under the temperature program such as 1 min at 80℃, with 10℃/min rate rose to 110℃, keep 1 min, in 20℃/min rate rose to 220℃, keep 1 min, run at 280℃, keep 5 min, it is obtained a better response time and area of IPBC. The linear correlation coefficient is greater than or equal to 0.999 in the concentration range of 0.5-2.0 mg/L. The detec-tion limit is 1.0 mg/kg, and the recovery is greater than or equal to 60%in the blank sample.
