Abstract	Researchers fabricated and characterized a series of Nb substituted magnetites; Fe3−xNbxO4. The magnetite inverse spinel structure and magnetic property were maintained in all the synthetized samples. They noted a significant decrease in crystal size and increase in specific surface area with increased Nb content, resulting in higher adsorption capacity of the samples. Results showed that incorporation of niobium into magnetite significantly improved the characteristics and effectiveness of the heterogeneous catalyst for Fenton treatment of recalcitrant effluents.
