Bioethanol wastewater contains complex inorganic and organic ions, posing a severe environmental problem. In this research, the removal of nitrate ion (NO3-) from bioethanol wastewater was conducted using ammonium polymers as adsorbents. Ammonium polymer was synthesized using the one-pot approach method using functional monomer with single thermal. This study aimed to analyze the performance of an ammonium polymer for removing nitrate ions (NO3-) from bioethanol waste, considering operational parameters (polymer mass, temperature, and contact time) through advanced characterization techniques and determining the isotherm model for predicting adsorption behavior. The results of FTIR revealed significant functional groups, including amine groups. SEM-EDX confirmed the effectiveness of adsorption by identifying each component, and elemental analysis confirmed the percentages of C, H, and N in the adsorbent. The optimal conditions for the adsorption process were achieved when 0.1 g of ammonium polymer was in contact with bioethanol wastewater for 60 minutes at 40oC with a removal efficiency of 96.32% and an adsorption capacity of 0.58 mg/g. The adsorption isotherm analysis followed the Temkin model.
