Synthesis and characterization of ammonium polymer for anion removal in aqueous solutions

Abstract

In a one-step thermal process using 2-[(methacryloyloxy)ethyl]trimethylammonium chloride (META), an ammonium polymer was successfully obtained for the removal of anions (nitrates, nitrites, and phosphates) from aqueous solutions. Ethylene dimethacrylate (EDMA) was used as a cross-linking agent. The effect of cross-linking agent, porogen, and polymerization time on the structure and physical properties of the obtained polymer was examined (FTIR, SEM, BET, elemental analysis). The optimal conditions for META synthesis were a monomer to porogen ratio of 20:80, 75% functional monomer content and a 12-hour polymerization time.

Isotherm Adsorption of Ion Phosphate from Vinasse Waste Using Quaternary Ammonium Polymer as Adsorbent in Term Effect of Temperature

“…Quaternary ammonium polymer produced through a one-pot approach polymerization process with optimum composition and conditions has been successfully used as an adsorbent (Rahayu et al, 2023). Before being filled into a cylindrical tube, the polymer solution consisting of 1.25 mL monomer META (C9H18ClNO2), 0.375 mL EDMA (C10H14O4), 0.35 mL ethanol (C₂H₆O), 1.4 mL poly (ethylene glycol) ((C2H4O)nH2O), 1.75 mL isopropyl alcohol (C3H8O), and 0.005 g AIBN (C8H12N4) was homogenized.…”

“…Certain heavy metals, both as ions and as organic molecules, can be adsorbed by this highly developed polymer. For the efficient adsorption of phosphate ions in aqueous solutions of 95.11%, a grafted polymer based on the monomer 2-[methacryloyloxy) ethyl] trimethylammonium chloride solution or META the one-pot approach method has been used to be synthesized (Rahayu et al, 2023). Furthermore, utilizing META to modify the surface of cocoa shells increased the proportion of phosphate ion adsorption by 92% (Rahayu et al, 2023).…”

According to Aini's (2023) study, adding quaternary ammonium to CH-T resulted in a 96% removal effectiveness of phosphate and nitrate ions.…”
