Effluents from the textile industry and artisanal dyeing contaminate water resources. The objective of this work is to eliminate the dye safranin from the aqueous medium by adsorption on natural materials. The clay used comes from Daloa in the center-west of Côte d’Ivoire. It is ground and then dry sieved on a column of sieves with a diameter of between 45 μm and 2 mm. The balls are made with the diameter fraction between 45 and 125 μm. Thus, 40 mL of distilled water is added to 100 g of clay powder. The balls obtained (approximately 0.5 cm in diameter) are dried in an oven at 60°C for 24 hours, then calcined in the oven at 500°C for 2 hours. The experimental device is a glass column 64.4 cm high and 2.9 cm inside diameter surmounted by a separating funnel containing the solution to be treated. The samples from the adsorption tests are analyzed using an AQUALYTIC 800 brand UV-visible spectrophotometer. Mathematical models are applied to model the breakthrough curves. The results showed that breakthrough time and adsorption capacity increase with bed height (60, 240 and 420 min respectively for 8, 16 and 24 cm) and decrease with flow rate (240, 90 and 30 min respectively). for 2, 3 and 4 mL/min). The modeling of the different breakthrough curves shows that the models applied are able to describe the entire dynamic behavior of the column.

Abstract: (french)
Les effluents de l’industrie textile et de la teinturerie artisanale contaminent les ressources en eau. L’objectif de ce travail est d’éliminer le colorant safranine du milieu aqueux par adsorption sur des matériaux naturels. L’argile utilisée provient de Daloa au centre-ouest de la Côte d’Ivoire. Elle est broyée puis tamisée à sec sur une colonne de tamis de diamètre compris entre 45 μm et 2 mm. Les billes sont confectionnées avec la fraction de diamètre compris entre 45 et 125 μm. Ainsi, 40 mL d’eau distillée sont ajoutés à 100 g de poudre d’argile. Les billes obtenues (environ 0,5 cm de diamètre) sont séchées à l’étuve à 60 °C pendant 24 h, puis calcinées au four à 500 °C pendant 2 h. Le dispositif expérimental est une colonne en verre de hauteur 64,4 cm et de diamètre intérieur 2,9 cm surmontée d’une ampoule à décanter contenant la solution à traiter. Les échantillons issus des tests d’adsorption sont analysés au spectrophotomètre UV-visible de marque AQUALYTIC 800. Des modèles mathématiques sont appliqués afin de modéliser les courbes de percée. Les résultats ont montré que le temps de percée et la capacité d’adsorption augmentent avec la hauteur du lit (60, 240 et 420 min respectivement pour 8, 16 et 24 cm) et diminuent avec le débit (240, 90 et 30 min respectivement pour 2, 3 et 4 mL/min). La modélisation des différentes courbes de percée montre que les modèles appliqués sont aptes à décrire l’ensemble du comportement dynamique de la colonne.
