Rapid detection method for heavy metal cadmium in rice

The invention provides a rapid detection method for heavy metal cadmium in rice, and relates to the technical field of chemical content analysis. The invention relates to a rapid detection method of heavy metal cadmium in rice, which comprises the following steps: respectively detecting by adopting a gradient standard use solution with the cadmium content of 0-100ng, and drawing a standard curve taking the absolute mass of cadmium as a horizontal coordinate and an obtained integral absorbance value as a vertical coordinate; the method comprises the following steps: crushing a rice sample, drying and combusting under an air condition, pyrolyzing and atomizing in a hydrogen-rich gas flow, determining an absorbance value, and calculating the content of the heavy metal cadmium in the sample according to a standard curve. The rapid detection method for cadmium in rice provided by the invention is a direct solid sample injection quantitative detection method without pretreatment, does not need any chemical reagent,
