摘　　要：根据GB/T 5009.156-2003,以水、乙醇、乙酸和正己烷作为食品模拟液,把聚丙烯纳米银复合材料浸泡在食品模拟液中,以时间和温度为变量,蒸干浸泡液后消解定容,用电感耦合等离子体质谱仪(ICP-MS)检测迁移出的纳米银的浓度。结果表明,接触材料中的纳米银在不同的模拟液体中的迁移量与温度和时间的变化成正比。The migration character of nano Ag was investigated by simulate testing in four food simulants including water, 4% acetic acids, 20% alcohol and n-hexane. The amount of the migrated nano Ag was determined by inductively coupled plasma mass spectrometry （ICP-MS）. The results showed the amount of nano Ag migrated increased gradually with increasing the migration temperature and time in all food simulants, and the migration in 4% acetic acid was largest and least in water and 20% alcohol.
