Rong Li

Abstract

The method for determination of sodium,potassium,calcium,magnesiun in environmental reference material by flame atomic absorption spectrometry(FAAS) was studied.Under the optimum conditions,the RSDs of sodium,potassium,calcium,magnesium were respectively 0.88%,0.93%,1.84%,5.13%.The recoveries of sodium,potassium,calcium,magnesiun were respectively 93.0%,94.0%,109.0%,110.0%.The method has simple operation,high-speed determining and accurate results.
