The current work is focused on the designing of a green interpenetrating polymer network (IPN) PA@polyAAm:AN using polyvinyl alcohol‐agar hybrid backbone and its subsequent conversion into an anion‐exchanger PA@polyAAm:AN‐AE through reduction of nitrile group in presence of LiAlH4. Further, the reduced form of IPN was quaternized using methyl iodide so that anion to anion exchange could take place between F− and I− anions. The primary objective of synthesizing an anion‐exchanger was to eliminate F− ions from contaminated water through the utilization of a prepared device. During the optimization of different experimental parameters for getting the optimal anion‐exchange capacity (AEC), the favorable conditions found were: pH, 9.0; contact period, 120 min; adsorbent dosage, 30 mg and initial F− ion concentration, 8.0 mg L−1. The pseudo‐second order kinetic model best described the F− ions adsorption kinetics, with a 0.97 R2 value. The rate constant (KF) was found to be 2.3, which further supported the validity of the Freundlich isotherm. Thus, the current study has remarkable potential with a 79.99% adsorption capacity for eliminating F− ions. Moreover, the ecofriendly anion‐exchanger prepared was found effective in the removal of F− ions from aqueous medium up to four cycles during reusability analysis.
