| Abstract: | The method of continuous extraction with ultrasonic was used to extract the different chemical forms of Ca , Mg, Cu, Mn, Co and Cr in maize, In the extraction of maize, related elements content in different speciation was detected by atomic absorption spectrometry. The results showed that there were significant differences of various forms of ratio of elements Ca, Mg, Cu, Mn, Co and Cr in different regions of the maize, and there was a certain characteristic of origin. |
