Abstract
The Objective of our study is the valorization of clay of the western region of Algeria. The experimental study is the preparation and characterization of Antimony pillared materials using SbCl3 solution as pillaring agent. The synthesis of pillared clay was characterized by different techniques namely (FTIR, XRD and XRF) and physic-chemical analyzes (CEC, the acid index, specific surface area, average pore diameter, and volume mass). The intensity of the Bands assigned to Si-O and Al-O Vibrations were slightly reduced on pillaring process. The decrease in intensity is due to the process of dehydroxylation produced during pillaring. The d-spacing for the intercalated and pillared bentonites is 38.199 A° and 30.057 A°, respectively. The specific surface area of pillared and natural bentonite is 365.11 and 68.25 m2 g-1 respectively. With determined specific properties, modified clays are highly reactive matrices that can be used as adsorbents in the process of depollution of industrial wastewater.
