✦ Synopsis

A normal-phase liquid chromatographic method for the selective determination of molybdenum with N-benzoyl-N-phenylhydroxylamine is described. The molybdenum(W) complex was preconcentrated by extraction into chloroform and injected onto a nitrile column for chromatography.

The mobile phase was a 0.075 M solution of reagent in chloroform (stabilized with amylene). The detection limit for molybdenum by the proposed method was 0.88 ng for a phase volume ratio of 2O:l (aqueous to organic). Molybdenum has been determined in several samples with satisfactory accuracy and precision.
