Etude experimentale et numerique de l'elimination de la metformine chlorhydrique des eaux usees par la bentonite intercalee

Abstract

The objective of this work is to study the power of elimination of metformin.HCl by intercalated bentonite. Adsorption is an economical and easy to implement technique. It is widely used in the removal of pollutants from aqueous solutions. In order to preserve the environment, intercalated Maghnia bentonite has been used to test its effectiveness in reducing the level of hydrochloric metformin. Contact time, initial concentration, temperature, pH are parameters that influence the adsorption process. This process follows a pseudo-second order kinetics and is described by the Langmuir model. Thermodynamic parameters have also been determined.
