Indirect determination of arsenic by flotation

An indirect method of arsenic determination in the submicrogram range via the determination of molybdenum is presented here. High sensitivity is achieved by combination of the chemical amplification during formation of dodecamolybdoarsenic acid (arsenic: molybdenum ratio 1 ∶ 12) with multiplication due to the formation of ion-association complexes during flotation-spectrophotometric
