Abstract
The orthogonal array design methods were applied to analyze the influence of H2O2 volume/HNO3 volume/microwave digestion time three factors and their interaction on the extraction of Cd，select an optimized progress to extract Cd from shrimps. The experimental results showed that when H2O2 volume was 1.0 mL, HNO3 volume is 5.0 mL, microwave digestion time was 13 minutes and 46 seconds, under these conditions，the contents of Cd reached 0.497 mg/kg. Determination of GBW10050 (big shrimps) showed that contents of Cd have the same results with standards values. Method limits of detection were obtained within the range of 0.01 μg /kg，the precision for this method was better than 5%. It allowed simple, rapid, sensitive and accurate determination of Cd in shrimps.
