| description | By testing the parameters of graphite digestion instrument， the effects of graphite digestion method and microwave digestion method on the determination of total arsenic in rice were analyzed and compared.The results showed that the RSD of rice standard sample digested by graphite digestion method was 5.25%～6.86%， and the relative error between the test result and the standard value was 5.66%～7.55%. The RSD of rice standard sample digested by microwave digestion method was 8.67%～12.26%， and the relative error was 17.96%～21.7%. The accuracy and precision of graphite digestion method are higher than that of microwave digestion method. |
