TartrazineIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The coal ash (Φ) was used as an adsorbent for the removal of tartrazine from aqueous solution at room temperature. The adsorption capacity of tartrazine increased as the adsorption time was increased and then remains constant after 30 min adsorption duration. It was found that the U removed more than 40% of tartrazine from the aqueous solution within 1 h contact time. The equilibrium adsorption was also analyzed by Langmuir isotherm and it was found that the data followed the Langmuir isotherm models.

Titre : Removal of tartrazine from aqueous solution by activated coal Type de document : texte imprimé Auteurs : M. Ishaq, Auteur ; K. Saeed, Auteur ; I. Ahmad, Auteur ; M. Shakirullah, Auteur ; S. Nadeem, Auteur Année de publication : 2010 Article en page(s) : p. 13-17 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Tartrazine Coal Adsorption Morphology Scanning electron microscopy Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Removal of industrially important Tartrazine dye from aqueous solution was carried with virgin and variously activated coal samples at room temperature. The morphological study indicated that the number of coal particles was increased when the coal was evacuated at 200°C while aggregated form was observed at 400°C evacuation temperature. The coal particles were again formed at 600°C evacuation temperature. The coal, which was evacuated at 400°C, adsorbed less Tartrazine than the coal samples which were evacuated at 200 and 600°C. This might be caused by the aggregation of the coal particles at 400°C (because of the plastic range of coal swelling), which results in a decrease of the coal surface area. The obtained adsorption data were also fitted to Langmuir and Freundlich isotherms, which followed both Langmuir and Freundlich isotherms models.
