摘要

将传统的样品制备方法，如煅烧和酸消化，与另一种方法:碱性溶解和超声辅助提取进行了比较。应用上述样品制备方法和火焰原子吸收光谱法(FAAS)测定奶粉样品中的Mg和Zn，对上述方法进行了评价。结果表明，超声辅助提取法不适合提取锌和镁，而TMAH碱性增溶法只适用于Mg的提取。

Determination of Zn and Mg in Milk Powder Samples Using Conventional and Alternative Sample Preparations and FAAS

: Conventional procedures for sample preparation, such as calcination and acid digestion, were compared with an alternative procedure: alkaline solubilization and ultrasound-assisted extraction. The procedures were evaluated by the application of the mentioned sample preparation and subsequent determination of Mg and Zn in milk powder samples by flame atomic absorption spectrometry (FAAS). The results indicated that ultrasound-assisted extraction was not suitable for Zn and Mg extraction, whereas alkaline solubilization using TMAH was efficient only for determination of Mg.
