Abstract

Objective: The general objective of this work is to study the adsorption capacity of two heavy metals (Pb²⁺, Cu²⁺) by the fine sodic fraction of the clay collected in the locality of Loukoléla. Materials and Methods: The kinetics of adsorption allowed us to find a time of equilibrium of copper, lead with the mont-Na. The influence of the pH was carried out in basic and acid medium, the adsorption isotherm is obtained by drawing the curve of the adsorbed quantities according to the concentration at the equilibrium, the Langmuir isotherm was used to write the adsorption of copper and lead. Results: The equilibrium time is reached at t =20 min with an adsorption quantity of 64 mg/g for Cu²⁺; for the Pb²⁺ ion the equilibrium is reached after 25 minutes with an adsorption quantity of 43.2 mg/g of fixed metal. Two models were used for the modelling of this work, namely the Langmuir model and the Freudlich model. This study shows that the Langmuir model gives better results than the Freundlich model with a maximum adsorption capacity of the monolayer of 653.12 mg/g for Cu²⁺ and 100.388 mg/g for Pb²⁺, Loukoléla clay shows high affinities with copper particles compared to lead particles. These results show that Loukoléla clay can be used as an adsorbent for metallic pollutants.
