Abstract
A colorimetric procedure is described for the determination of iron in plant material by using sulphonated 4, 7-diphenyl-1, 10-phenanthroline. The method may be applied directly to the AutoAnalyzer, and gives good and reproducible recoveries over a wide range of added iron. The possibility of low recoveries of iron resulting from the wet digestion of material in the presence of sulphuric acid is discussed.Keywords
