食品中有害元素的富集与分离及其在一些光学及电化学分析方法中的应用

Separation and Enrichment of Harmful Elements in Food and Their Application to Some Optical and Electrochemical Analytical Methods

摘要: 对用不同离子交换树脂及活性氧化铝分离和富集食品中的一些有害元素,包括铅、镉、汞、硼、铀、钍、碘、氟和铬(Ⅵ)的方法作了详述,着重介绍了上述分离与富集方法与一些光学及电化学分析方法相结合,如电感耦合等离子体原子发射光谱法、电感耦合等离子体质谱法、原子吸收光谱法和离子选择电极等,达到了消除基体(如大量钠等)干扰和降低测定的检出限等目的,解决了一些疑难问题(引用文献35篇)。

Abstract: A review on the separation and enrichment of harmful elements ［including Pb, Cd, Hg, B, U, Th, I, F and Cr(Ⅵ)］ in food samples was reported with special emphasis on their application to some optical and electrochemical analytical methods (e.g. ICP-AES, ICP-MS, AAS, ISE and etc.), aiming to eliminate matrix inter ferences (e.g. macro amounts of sodium and etc.), and to lower detection limits of determinations (with 35 ref. cited).
