A method was established for determination of potassium and sodium contents in electrolyte drink by flame atomic emission spectrometry （FAES）. The detection limits of K and Na were 0.004 22μg/mL and 0.002 16μg/mL respectively. And the relative standard devitation （RSD） were 91.1%~100.9% and 93.0%~102.8%respectively. The method is simple, rapid, accurate, reproducible, and without using extra light source. Its experimental results are as closely as that of the flame atomic absorption spectrometry （FAAS）.
