A method of X-ray fluorescence spectrometer was established for rapid screening of cadmium in rice.MethodsThe rice was detected by X-ray fluorescence spectrometer after crushed.ResultsThe limit of detection and quantification of detection were 0.035 and 0.094 mg/kg, the standard deviation of accuracy was 0.015 5 and the value of t-test was 0.30. Chi-square value of repeatability was 5.32, and the chi-square value of stability was 11.07 within 12 h. The standard deviation was 0.021 3 between two instruments.ConclusionThe results indicated that the X-ray fluorescence spectrometer could meet the standard requirements of cadmium in rice. The accuracy, repeatability and stability of instrument could meet the requirement of rapid screening. A new rapid screening method for cadmium in ricewas developed. It provided technical support for purchasing grain in grassroots grain depot, acceptance check and supervision of food raw material.
