Abstract
Incorporation of oxygen to crystalline zeolitic chromosilicates, with oxidation of anchored CrIII to non-interacting CrVI 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.Keywords
