| 摘 要： | 建立了微波消解—电感耦合等离子体质谱法测定海参中Cu,As,Cd,Hg,Pb 5种有毒元素含量的方法,采用In元素为内标,利用其回收率对以上5种元素的测定结果进行校正,该方法变异系数(CV%)为0.2%~4.0%,In元素加标回收率为96.7%~104.5%,说明该方法灵敏度高,结果准确可信。利用该方法对10批不同市售海参中5种有毒元素含量进行了测定,结果表明10批市售海参中的As含量均超标,部分批次海参中的Cd、Pb超标,说明市售海参确实存在有毒元素超标的问题。 |

| Abstract: | A method based on microwave sample digestion and inductively coupled plasmamass spectrometry（ICP--MS） detection was established for determination of Cu,As, Cd, Hg and Pb in holothurian sold on the market. Indium was used as internal standard element to calibrate the results of determination of these five elements. Determination limits of these five elements were in the range of 0. 006- 0. 063 vg/g , coefficient of variation（CV % ）were in the range of 0.2 % --4.0 % , and the recovery of In was in the range of 96.7 %- 104.5 %. The method has been applied to determine the five poisonous elements in ten holothurian samples sold on the market. The results indicated that the over-standard problem of poisonous elements in holothurian sold on the market existed. The content of total arsenic was over standard in all the ten samples, but the over standard problem of lead and cadmium was only found in part of the samples. |
