Abstract:

 The flowering of industrial activities is generally accompanied by a phenomenon of effluent discharges containing many dangerous chemical substances. These water pollutants include Methylene Blue (BM) and Orange II (OII), which can cause human health problems and disrupt the balance of the aquatic system. Several effluent treatment methods exist but remain expensive and therefore inaccessible for developing countries such as Côte d'Ivoire. The present work aims at the adsorption removal of these two toxic dyes on inexpensive plant biomass in this case deactivated lichens. The various parameters influencing the adsorption such as the contact time, the initial concentration of the solution and the temperature, were studied. The kinetic study has shown that the biosorption process of BM and OII suitably follows pseudo-order two kinetics. The adsorption isotherms have shown that biosorption of BM is best described by the Freundlich model and that of OII by the Langmuir model. The thermodynamic study of the lichen-dye system showed that the adsorption process of the two dyes is spontaneous, endothermic for BM and exothermic for OII. The results obtained suggested a process of chemisorption and physisorption. These results show the possibility of treatment of colored effluents by lichens.
