Abstract: In this paper the Ca and Mg in salt were detected by flame atomic absorption spectrometry (FAAS). The results showed that Beer’s law is kept in the range of 0.0~20.0μg/ml of Ca(Ⅱ) and 0.0~2.4μg/ml of Mg(Ⅱ).The relative standard deviation (RSD) is 2.0%~2.2%. The relative error is 2.3%~4.4%.

Key words: salt, calcium, magnesium
