E. aFluorometric analysis of selenium in plants.h[electronic resource] c1969 aA previously reported method for the determination of Se in biological materials has been slightly modified for use on plant materials. Based on a wet digestion and measurement of the fluorescence of the piazselenol formed on reaction with 2,3 diaminonaphthalene, the method as used is sensitive to about 0.02wg Se. The results of several studies of the method, including a collaborative study, are reported. This method is recommended for adoption as official first action. aEstimation aFluorescence aMethodology aPlant nutrition aSelenium aTrace elements aPlanta aSelĂȘnio aAnalise Fluorometrico aAnalysis aPhotometry tJournal of Aoac Internationalgv. 52, n. 3, p. 627-634, 1969.
