Properties and analytical application of a new membrane electrode sensitive to molybdenum(VI).

A new liquid molybdenum(VI)-sensitive electrode with a membrane based on a solution of the molybdenum(VI)-N-benzoyl-N-phenylhydroxylamine chelate is proposed and its electrochemical behaviour and applicability have been critically investigated. The transfer of molybdenum(VI) across the water-organic solvent interface and across the membrane has been studied by use of sodium molybdate labelled with (99)Mo, and the response mechanism of the electrode is discussed.
