Abstract: The copper in pig's haslet was studied by flame atomic absorption spectrometry. It was found that the microwave digestion effect was satisfzctory under the following conditions: 0.5 g of pig's haslet sampling, 0.5 h of preliminary digestion, V_HNO3:V_H2O2=1:1, 3min of digestion time in mi-high fire microwave power. By this way, RSD was 0.47%～1.69% and the adding standard recovery was 96.%0～105.0%. The said method is characterized by low cost, and easy to handle, which makes it possible to find application in accurate and fast determination of copper.
