用硝酸-过氧化氢为消解液,微波消解前处理燕窝样品,采用电感耦合等离子体质谱(ICP-MS)测定样品中Pb、As、Cd和Cu含量。测定结果表明,4种元素方法检出限分别为0.006,0.013,0.002,0.011 mg/kg,平行样品检测结果的相对标准偏差小于3.9%,方法回收率在98%～102%。表明该方法具有快速准确的特点,适用于燕窝产品中重金属元素的检测。 The samples of bird’s nest were treated with nitric acid-hydrogen peroxide solution before microwave digestion, and the contents of Pb, As, Cd and Cu in the samples were determined by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that the detection limits were 0.006, 0.013, 0.002 and 0.011 mg / kg for the four elements respectively. The relative standard deviations (RSDs) of the parallel samples were less than 3.9%. The recoveries were between 98% and 102%. It shows that this method is rapid and accurate and is suitable for the detection of heavy metal elements in bird’s nest products.
