Dynamic Sorption Study of Paracetamol on New Sorbent Support Based on Granulated Polyethylene Waste

This present research relates to a comparative study of the dynamic sorption of paracetamol in a fixed bed column on a new category of sorbents based on a very available material which is” granulated polyethylene waste (WPEG)” and linear low-density polyethylene. The study is carried out by examining the effects of different parameters such as: pH, bed height and paracetamol concentration. Under the used conditions, all obtained results showed that the highest removal efficiency is obtained under the following optimal parameters (C₀=4mg/L, Q=2mL/min, H=7cm, pH=3). Thomas and Ogata-Bank models were used for modeling the optimal results. It was noticed that the Thomas method predicts the experimental results well with a correlation coefficient considered very satisfactory (0.96). The maximum sorption capacity obtained by the sorbent based on granulated polyethylene waste is approximately 115 mg/g, thus showing the great effectiveness of this sorbent in the elimination of paracetamol.
