title: Single-dose assay of ferrous ion in pharmaceuticals.
abstract: A method for assay of the ferrous ion in hematinics or multivitamin tablets is described. The method is based on the spectrophotometric measurement of the chromophore produced by reacting the ferrous ion with the highly specific chelating agent ferrozine. The method is proposed as an alternative to the redox methods in the USP and NF.
