A method useful for the determination of cadmium, cobalt, copper, iron, lead, manganese, nickel and zinc in diets is described. Organic matter is destroyed applying a wet procedure, and element content is measured by flame atomic absorption spectroscopy (FAAS) in the case of copper, iron, manganese, nickel and zinc, and by graphite furnace (GF-AAS) in the case of cadmium, cobalt and lead. The matrix interference study is carried out. Values found for linearity, detection and quantitation limits as well as accuracy show that the described method is useful to determine the elements taken into account at usual levels in diets.
本文描述了一种用于测定膳食中镉、钴、铜、铁、铅、锰、镍和锌的方法。采用湿法程序破坏有机物，对于铜、铁、锰、镍和锌，通过火焰原子吸收光谱法（FAAS）测量元素含量；对于镉、钴和铅，则通过石墨炉（GF-AAS）测量。进行了基体干扰研究。线性、检测限、定量限以及准确度的测定值表明，所描述的方法对于测定膳食中常见水平的上述元素是有用的。
