In the present study, we report the green synthesis of novel magnetically separable MgFe 2 O 4 nanoparticles using Cajanus cajan (L.) Millsp leafs via combustion method. The MgFe 2 O 4 were characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and UV-Vis spectroscopy. The crystalline structure of MgFe 2 O 4 NPs was con rmed via XRD electron micrograph and TEM showed that the MgFe 2 O 4 NPs were nearly spherical particles with particle size ranging between 5-15 nm. UV-vis DRS study showed the optical band gap of MgFe 2 O 4 NPs was found to be 1.0 eV. Microwaves (MW) assisted degradation of PCM-dolo drug on MgFe 2 O 4 were performed at different operating parameters such as time (0-30 min), drug concentration (PCM-dolo 50 mg/L), initial concentration of MgFe 2 O 4 (0 mg/L -110 mg/L), and microwave power (100W-600W) to obtained the residual absorbance of PCM-dolo on MgFe 2 O 4 . Experimental data was used to compute the degradation e ciency of PCM-dolo on MgFe 2 O 4 . The enhanced catalytic performance could be ascribed to the production of MW-induced active species, such as holes (h + ), superoxide radicals (•O 2 −) and hydroxyl radicals (•OH) in the degradation process. A possible degradation mechanism and pathway was proposed in MW/MgFe 2 O 4 system. Moreover, MgFe 2 O 4 as an eco-friendly catalyst could be easily separated and recycled by a magnet.
