| Abstract: | 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. |
