Salicylaldehyde Isonicotinoylhydrazone (SAIH) as a Specific Analytical Reagent for the Selective Extractive Spectrophotometric Determination of Molybdenum (VI) in Presence of Several Cations

Abstract

An extraction study of 36 cations with SAIH into isoamyl alcohol in the presence of EDTA, ascorbic acid and IN HC10₄ showed that only Mo(VI) gave a stable yellow colored complex extractable into the organic phase. This effect was used for the selective extractive spectrophotometric determination of Mo(VI) in the presence of other tested cations.
