Determination of molybdenum in plant materials using a rapid, automated method 1

Abstract
A method is described for the determination of Mo in plant tissue based on the catalytic action of Mo on the KI‐H2O2 reaction. An autoanalyzer with a modified de‐bubbling system and a long path length (50 mm) flow cell is used. Significant improvements in sensitivity have been made over previous methods and the procedure is sensitive enough to determine 5%) can be overcome by addition of appropriate amounts of chloride salts to the standard solutions.
