Abstract
X-ray method proved to be reliable, accurate and sensitive technique to study activated carbons defining its exhausted level with organic compounds. For the first time, the characterization of the exhaustion level of granular activated carbon (GAC) used in rum production applyed a method based on X-ray technology. Digital processing on X-ray radiography images from eight consecutive GAC layers of the industrial rum filter has been assessed. They were correlated with thermal desorption gas chromatography/ mass spectrometry (TD-GC/MS) chromatograms. The total of pixel detected in the radiographic X-ray images (grey-scale) is related with the total amount of organic adsorbed compounds in the exhausted GAC. The proposed method opens possibilities for the rum producers to improve the management and economical use of the activated carbon at industrial scale. This method is applicable to determine the saturation degree of all kinds of adsorbents used in the removal of organic compounds like dyes and pharmaceuticals in waste waters.
