STUDY ON THE DISTRIBUTION OF SELENIUM AND OTHER ELEMENTS IN CORN SAMPLES BY NAA AND BIOCHEMICAL TECHNIQUE

Biochemical technique was used to separate three kinds of proteins (albumin, globulin and gliadin) in corn samples froin high selenium areas and normal areas in Erxi autonomous region of Hubei Province, China. The contents of Se and other elements in these proteins were determined by neutron activation analysis (NAA). The results show that Se is enriched in corn proteins at high selenium area, while Cu, Al, Mn, V and Cl are also enriched in varying degrees.
