摘要
[Objective] This study aimed to analyze the contents of trace elements in potatoes from different production areas in Qinghai Province. [Method] By flame atomic absorption spectrometry （FAAS）, the contents of various trace elements in potatoes were determined. [Result] Potatoes contain abundant trace elements such as Cu, Zn, Fe, Mn, Ca, K and Mg. To be specific, the contents of Ca, K and Mg were relatively high. [Conclusion] By using FAAS, the relative standard deviation was 1.17%-2.75% and the recovery rate was 97%-99.5%, indicating accurate and reli-able results with high precision.
[目的]测定青海不同产区马铃薯中的微量元素。[方法]采用火焰原子吸收法测定马铃薯中微量元素的含量。[结果]马铃薯中含有丰富的 Cu、Zn、Fe、Mn、Ca、K、Mg 等微量元素，其中Ca、K、Mg含量较高。[结论]采用该方法，相对偏差在1.17%-2.75%之间，回收率在97%-99.5%之间，结果准确可靠，精密度较好。
