    Synthesize and Characterization of Polyimine and Its Application for Removing Amoxicillin from Polluted Water
    (Al-Quds University, 2025-05-15) Alaaeddin Jawadat Mohammedmousa Alsharif; علاء الدين جودات محمد موسى الشريف
    This study aimed to prepare and characterize crosslinked polyimine polymer and its efficiency in removing pharmaceutical contaminants, specifically amoxicillin and paracetamol, from polluted water. A polyimine was prepared by reacting 1,4-diaminobutane, glutaraldehyde, and tris(2-aminoethyl) amine in a fixed molar ratio of 1:1:0.05. The FTIR and DSC were used to analyze the chemical structure and thermal behavior of the polyimine. Adsorption capacity was determined by HPLC, and the data were examined using both Langmuir and Freundlich isotherms. The impact of pH on adsorption was also studied. Despite the exciting application of polyimine-polymers in molecular filtration, no previous study had examined their efficiency in pharmaceutical removal from contaminated water. The FTIR results indicated the successful synthesis of polyimine. The DSC results suggested a crosslinked structure and a thermoset-like behavior due to the lack of thermal transitions. In addition, the polyimine’s insolubility in organic solvent supported the high degree of crosslinking within its structure. The reattached polyimine grains in aqueous environments indicated a self-healing property. The amoxicillin removal reached 63% at pH 7, while the removal of paracetamol was negligible. Experimental data fitted both to the Langmuir and the Freundlich models, suggesting a partially heterogeneous surface. The research findings suggested further modifications for polyimine to enhance its adsorption efficiency. Such modifications, which will increase the positively charged species N⁺, could be applied by increasing the crosslink density or introducing quaternary ammoniums. In addition, the study demanded that toxicological evaluation should be considered before any large-scale environmental application.
