The maize sample contained 18 ppm and the rice samples an average of 3.6 ppm selenium. After they were ground to obtain a fine flour, this was acid hydrolyzed with hydrochloric acid in an inert atmosphere and the hydrolyzates chromatographed on columns of Dionex DC6A resin. The results indicate that the majority of the selenium is present as selenomethionine in both rice and corn.展开更多
