电感耦合等离子体质谱(ICP-MS)仪分析回收油脂 与食用植物油中27种元素含量的差异Difference of 27 elements in recycled oils and edible vegetable oils analyzed by inductively coupled plasma mass spectrometer (ICP-MS)
利用电感耦合等离子体质谱(ICP-MS)仪对回收油脂与食用植物油中27种元素含量进行分析检测,了解回收油脂与食用植物油中27种元素含量的差异,以此鉴别回收油脂与食用植物油。采集合格食用植物油样品22份,回收油脂样品120份,经微波消解后,进入ICP-MS仪检测27种元素含量,结合偏最小二乘法判别分析进行元素差异分析,找出不同类型回收油脂与食用植物油的特殊差异元素。结果表明:Co、Cu、Fe、Na、Mn在未精炼回收油脂和食用植物油中的含量差异较大,可以作为鉴别未精炼回收油脂和食用植物油的指标元素;Fe、Cd两种元素在精炼回收油脂和食用植物油中的含量差异较大,可用于精炼回收油脂的鉴别;Cr、Cd、...
