| 摘 要： | 建立了模拟物中有害金属元素的电感耦合等离子体质谱测定方法（ICP-MS）。采用4种不同的模拟物替代食品,浸泡与食品接触的塑料包装材料,目的在于研究包装材料中有害金属元素的迁移情况。分别采用食品模拟物（乙酸、水、乙醇和正己烷）浸泡塑料包装材料,采用电感耦合等离子体质谱仪进行测定,并优化了仪器的条件。乙酸和水的浸泡液可直接导入电感耦合等离子体质谱仪进行检测,正己烷经过减压蒸馏后用2%硝酸定容,乙醇溶液经过电热板驱赶后采用2%硝酸定容,采用外标法定量。该方法的加标回收率在97.1%～108.9%之间、精密度在1.0%～3.9%之间,均满足实验的要求。

| Abstract: | The method for the determination of harmful metals in food simulants by inductively coupled plasma mass spectrometry(ICP-MS)was proposed.Food was alternatived by four different food simulants,soaking in contact with food plastic packaging materials.Food simulants were used(acetic acid,water,ethanol and hexane)soaked plastic packaging materials,were determined by inductively coupled plasma mass spectrometer,and optimize the instrument conditions.Acetic acid and water soaking solution can be imported directly... |
