Abstract This study utilized the magnetic Fe 3 O 4 ‐MnO 2 composite for As(III) removal by Box–Behnken design (BBD) model based on response surface methodology. The main objective of this was to reduce operational runs with help modeling maximum accurate output and oxidized toxic from As(V) MnO , after that adsorbed surface. had a good area (247.09 m /g), property (16.50 emu/g), mesoporous nature. Under batch‐optimized conditions, as obtained (0.190 g dose, initial concentration 10.34 mg/L pH 3.2) about 96% removed aqueous solution.
