摘    要:采用微波消解技术对以聚乙烯、聚丙烯为原料制作的食品容器、食品包装薄膜进行预处理,确定了溶样酸介质及其用量、微波消解温度、时间等关键因素,建立了一种快速测定聚乙烯、聚丙烯材料中铬、锆、钒和铪含量的电感耦合等离子体原子发射光谱法。实验结果表明,5mL硝酸和1mL过氧化氢的混合溶液即可实现样品的完全消解,同时通过优化光谱分析条件,得到铬、锆、钒和铪的检测限分别为1.0 mg/kg,0.7mg/kg,0.7 mg/kg,1.4 mg/kg。该法加标回收率在88%-103%之间,相对标准偏差(n=3)为0.84-6.4%。用于实际样品的测定,所得结果与标准样品的参考值相符。

关 键 词:电感耦合等离子体原子发射光谱法  聚乙烯  聚丙烯
