  ABSTRACT: This work falls within the general framework of the valorization of the clays of Ivory Coast in order to propose innovative solutions in the resolution of certain problems related to development such as the depollution of water. Its main objective is therefore to study the physico-chemical properties of two Dabou clays with a view to using them in chemical processes for the treatment of dyeing wastewater. The results of the chemical analysis and the ray diffraction showed that the DAB 1 and DAB 2 samples are clays of the kaolinitic type consisting mainly of kaolinite with 51.17% for DAB 1 against 65.81% for DAB 2 and quartz with respectively 41.76% and 25.8% for DAB 1 and DAB 2. They also contain relatively large amounts of goethite with 9.96% for DAB 1 and 12.8% for DAB 2. The specific surfaces measured in both samples are greater than 25 m2/g. All the results of the physico-chemical characterization, in particular the presence in significant quantity of clay minerals, the presence of iron compounds and the large specific surface area of both samples, allow the conclusion that they can be used in adsorption studies and in the heterogeneous Fenton process for water treatment.
