| Abstract: | The contents of K, Ca and Mg in 76 blueberries are determined by Microwave Digestion—Atomic Absorption Spectrum (AAS) method. The experimental results indicate that,the K, Ca and Mg contents were 0.093 % ~5.06 %, 0.131 % ~0.826 % and 0.048 % ~0.246 % in 95% of blueberries, respectively. In addition , this method exhibited spike recoveries for 3 mineral elements were 96.23% ~102.03% and RSDs of sample results were 0 ~9.07%, with good accuracy and precision. |
