建立了同时测定食品塑料包装材料中9种紫外光稳定剂含量的高效液相色谱方法.样品用甲醇-乙酸乙酯混合溶剂超声提取,经固相萃取小柱净化后,以ZORBAX SB-C18柱(250mm×4.6 mm,5μm)为分离色谱柱,甲醇和水为流动相,梯度洗脱,以310 nm为检测波长进行定性、定量分析.该方法前处理简单、易操作,9种紫外光稳定剂分离效果良好.9种紫外光稳定剂在0.2~10 mg/L范围内呈良好的线性关系,线性相关系数大于0.999;方法检出限为0.05 ~0.1 mg/L;实际样品中的加标回收率为70.2%~89.0%,相对标准偏差为0.4%~4.5%.该方法简单、准确,能够满足食品塑料包装材料中紫外光稳定剂的检测要求.
