Abstract: Incorporation of oxygen to crystalline zeolitic chromosilicates, with oxidation of anchored Cr(III) to non-interacting Cr(VI) species, has been confirmed by photoacoustic spectroscopy; the dichromate anion being extracted from the chromosilicate with water and identified by precipitation of AgCrO4 and oxidation to CrO5.
