The importance of molybdenum, in industry, in life processes, etc., necessitates ac curate and precise analytical methods to determine its presence and its concentra tion in a variety of samples. With different samples molybdenum is present, as a major constituent, as a minor constituent, as one of several alloying components, as a trace element, and possibly in different oxidation states. The analyst is required to develop more selective and sensitive procedures for determining molyb denum in any sample type and new and improved methods for molybdenum are appearing in the literature at an...
