Abstract:

Pharmaceuticals as emerging pollutants have gained considerable attention due to their notable features such as low biodegradability, high persistence and facile bioaccumulation. Paracetamol was identified among various non-steroidal anti-inflammatory pharmaceutical compounds. It has been reported in existing literature that water samples frequently exhibit the presence of Paracetamol (PCT) pharmaceutical molecules. Different strategies have been put in place to address this problem in recent times. Various methods have been devised to reduce the occurrence of contaminants in water, amongst which the process of photodegradation has been prominently underscored. The process of degradation caused by exposure to Ultra-Violet (UV) irradiation, as well as the adsorption process is all widely researched and utilized techniques in the field of environmental engineering. These methods have demonstrated considerable efficacy in removing a variety of contaminants from water and wastewater. As such, they continue to be of significant interest to researchers and practitioners in the field. The present study concerns the study of the adsorption in batch mode of paracetamol by the waste resulting from the extraction of the essential oil of Mentha Spicata (WEM), by Linear Low Density Polyethylene (LLDPE 118WJ) and by the Waste Polyethylene Granulated (WPEG). The waste used (WEM) was characterized by physico-chemical and structural methods (FTIR). A kinetic experimental study of the adsorption of paracetamol on the studied materials in batch mode was carried out with a modeling of the experimental results. The findings reveal that the pseudo-second-order model effectively fitted the kinetic profile of paracetamol sorption on the studied materials, as indicated by the relatively reduced values of the normalized standard deviation. Obtained results demonstrated the effectiveness of these materials for the adsorption of paracetamol in batch mode (qe=133.25 mg/g for LLDPE, qe=118.91 for DPEG, qe=84.74 mg/g for DEM).
