Spectroscopic analysis of the sediments from the treatment of chromic wastes using ashes from the fluidised bed combustion of coal

Kulczycki A., Kowalski Z., Wzorek Z., Kozak A.

Polish Journal of Chemical Technology

2004

Vol. 6, nr 1

27-30

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.
