| Abstract: | Milk powder sample was digested with mixed acids and supersonic wave,and zinc concentration in the digested sample was measured by flame atomic absorption spectrometry. The result showed that by using this method of digestion accurate result was obtained with high reliability,low cost,less time consuming and less waste discharging comparing with the conventional digestion methods,such as dry-ashing and wet-digestion. |
