Abstract
This work is part of the valorization of clay, one of the natural and abundant resources in the regions of Ivory Coast, particularly in Daloa. The objective of this work was to characterize a clay from the city of Daloa for its future use in the field of liquid effluent treatment. Analysis were carried out using X – ray diffraction and scanning electron microscopy (SEM) coupled with energy dispersive X – ray spectroscopy (EDX). The results reveal that this clay is compose of dickite – 2M1 and halloysite – 7 Å, with significant quantities of quartz, and traces of titanium dioxide, iron oxide an aluminium. EDX analysis showed the presence of the chemical elements O, Al, Si, Fe, P and Ti. Furthermore, the use of this clay could be useful in wastewater treatment by adsorption.
