Abstract
A normal-phase liquid chromatographic method for the selective determi nation of molybdenum with N-benzoyl-N-phenylhydroxylamine is described . The molybdenum(VI) complex was preconcentrated by extraction into ch loroform and injected onto a nitrile column for chromatography. The mo bile phase was a 0.075 M solution of reagent in chloroform (stabilized with amylene). The detection limit for molybdenum by the proposed met hod was 0.88 ng for a phase volume ratio of 20:1 (aqueous to organic). Molybdenum has been determined in several samples with satisfactory a ccuracy and precision.
