The paper presents a spectroscopic analysis of the precipitate from the treatment of chromic wastes using ashes from the fluidised bed combustion of coal. A complete identification of the phase components of precipitate, originated from the Cr(III) waste neutralisation carried out by the infrared and Raman spectroscopy was performed. Based on a similar analysis of pure ash, the assignment of bands of these spectra was performed. A preliminary discussion of results was made from the point of view of nature of Cr(III) binding in ash.
