Microwave digestion-inductively coupled plasma emission spectrometry ( ICP-AES ) developed for the determination of total arsenic content in food detection methods was established, by detection method of error as well as the stability and repeatability of the method of verification, the method detecting instrument testing parameters and arsenic in the process of the analysis of the line was determined. The detection method repeatability RSD value was 2. 8%, the recovery was between 94. 6% ~101. 5%, the detection limit was 0. 018 mg/kg. The test method of sample preparation is simple and has good accuracy and precision, pollution-free and testing process, to detect the total arsenic content in the food provides a rapid and accurate method.
