The purpose of this study was to eliminate phosphate (P) from wastewater using MnFe2O4 nanoparticles. BET, TGA/DTG, FTIR, SEM, TEM, VSM, XRD and EDX/Map analyses were used to determine the MnFe2O4 surface properties. The specific surface area of the adsorbent was 196.56 m2/g and VSM analysis showed that the adsorbent has a ferromagnetic property. The maximum P sorption efficiency using MnFe2O4 (98.52%) was achieved at pH 6, temperature of 55 °C, P concentration of 10 mg/L, time of 60 min, and sorbent dosage of 2.5 g/L, which is a significant value. Also, the thermodynamic study indicated that the P sorption process is spontaneous and endothermic. Moreover, the utmost sorption capacity of P using MnFe2O4 was 39.48 mg/g. Besides, MnFe2O4 can be used for up to 6 reuse cycles with high sorption efficiency (>91%). Also, MnFe2O4 was able to remove phosphate, COD, and BOD5 from municipal wastewater with considerable removal efficiencies of 82.7%, 75.8%, and 77.3%, respectively.
