| 摘 要： | 采用高压密封硝化罐消解样品,应用ICP-AES法测定鲍鱼、海参中Fe,Ca,Mg,Zn,Sr,Se,Hg,Cd等15种微量元素的含量,以正交实验设计方案,通过方差分析选择最佳的实验操作条件,将数理统计与化学方法相结合,以极少的实验次数获得更多的信息.该方法简单、快速、灵敏度高,准确性好,且能多元素同时测定,另外对环境污染小.此方法回收率在91.0%～110.0%之间,相对标准偏差小于3.55%.实验结果表明:鲍鱼、海参中均含有丰富的Fe,ca,Mg,Zn,更含有Se,Ge,Sr,Cu等对人体有益的微量元素,是营养价值极高的海产品,但同时由于目前环境污染较严重,环境对海水的污染也不容忽视.当海域受到污染时,有害物质沉积于鲍鱼、海参体内,使其有害重金属含量偏高,人们食用时需要慎重.

| Abstract: | Abalone and sea cucumbers are useful,which is related with trace elements in them.In the present paper,using high-pressure sealed nitrifying pots for digestion of samples,Orthogonal test was applied to the determination of 15 kinds of trace elements in abalone and sea cucumber such as Fe,Ca,Mg,Zn,Sr,Se,Hg,Cd etc by ICP-AES.The orthogonal table of L 16(4 4) and experiment programs were designed.More information could be obtained with a small number of experimental times by combining chemistry with mathematic... |
