The method for determination of trace metals such as calcium and iron in red wine with air - acetylene flame atomic absorption spectrometry is simple and fast. Samples were dealed with microwave digestion method,the absorption of calcium and their concentration showed a linear relationship. Respectively, their linear correlation coefficients were 0. 9982, 0. 9992. The relative standard deviation was less than 5% and the recovery was from 95% to 105%.
