Treatment of Water Loaded with Pharmaceutical Residues Using a Natural Material

A new form of water pollution threatens countries, hospital effluents and the pharmaceutical industry, are the main sources of emission of pharmaceutical residues into the environment and water sources in particular. In the present work, we try to study the adsorption and elimination of amoxicillin in an aqueous solution on activated sodium bentonite . Our materials were analyzed and characterized by various methods, including infrared spectroscopy, X-ray fluorescence spectrometry and textural measurement of specific surface area (BM method), pH measurement, measurement of cation exchange capacity, moisture content, measurement of swelling index and determination of zero charge point pH. Optimization of certain parameters influencing the adsorption process, such as : contact time, quantity of adsorbent involved, pH of the medium, temperature, this study was carried out by monitoring the influence of physico-chemical parameters and modeling adsorption kinetics and thermodynamics, and from the results we can conclude that there is monolayer adsorption followed by saturation and multilayer adsorption of Lamoxuciline on activated clay. . finally, the ΔH values show that the adsorption reactions are exothermic.
