Issue Date: | 2018 | Publisher: | SPRINGER INTERNATIONAL PUBLISHING AG | Source: | JOURNAL OF ANALYTICAL SCIENCE AND TECHNOLOGY, 9 (Art N° 1) | Abstract: | Background: X-ray methods have proven to be reliable, accurate and sensitive techniques to study activated carbons in order to define its porous structure and functionality groups. Methods: For the first time, the characterization of the exhaustion level of granular activated carbon (GAC) used in rum production applying methods based on X-ray technology has been explored. In this work, the exhaustion degree of GAC from a target rum "filter" using X-ray radiography is evaluated. Digital processing techniques on X-ray radiography images from eight consecutive GAC layers of the industrial rum filter have been assessed. Results: The exhaustion profile for the rum "filter" applying X-ray radiography images processing is 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. Conclusion: The proposed method opens possibilities for the rum producers to improve the management and economical use of the activated carbon at industrial scale. The proposed technique can be applied in the assessment of other adsorption systems such as: determining the poisoning level of catalyst material, the GAC exhaustion level in organic polluted water treatments, and the GAC regeneration degree and exhaustion studies on hemo-perfusion GAC cartridges. | Notes: | [Puente Torres, Jeamichel] Univ Oriente, Fac Elect Engn, Santiago De Cuba, Cuba.
