摘要
采用液相色谱对鞋类及鞋类部件中苯乙酮残留量的测定进行研究,以甲醇为萃取溶剂,采用超声萃取法提取鞋类部件中EVA和PU材料中的苯乙酮,结果表明:方法线性范围为0.352~35.2 mg/L,方法检出限为0.14 mg/kg,加标回收率为90.40%~94.91%,相对标准偏差为2.25%~6.36%。本试验方法操作简便、快速、准确,适用于鞋类产品中EVA和PU的检测。
The determination of acetophenone residues in footwear and footwear components was studied by liquid chromatography.Acetophenone in EVA and PU materials was extracted by ultrasonic extraction with methanol as extraction solvent.The results showed that the linear range of the method was 0.352-35.2 mg/L,the detection limit was 0.14 mg/kg,the recovery was 90.40%-94.91%,and the relative standard deviation was 2.25%-6.36%.The test method was simple,rapid and accurate,and was suitable for the detection of EVA and PU in footwear products.
