Abstract
The metal ferrites (MFs) and their composites occupied a broad area of research in wastewater treatment because of their adsorptive, magnetic, and catalytic nature. This is due to their large surface area, high stabilities (for thermal, chemical, and mechanical stress), tuneable chemical composition, variety in size and shape, controllable magnetic properties, etc. The graphene (G) and graphene oxide (GO) (due to their exceptional electrical, mechanical, and thermal properties as well as extraordinary surface area) are performing excellently in wastewater treatment to remove/degrade several contaminants, both organic and inorganic. The composites of G/GO with metal ferrites are among the emerging candidates for wastewater treatment due to adsorption, photocatalytic degradation, and synergistic effect of adsorption-enhanced degradation, which offers excellent removal/degradation of contaminants along with easy magnetic separation. This chapter provides an excellent overview for the synthesis, characterization, and applications (in wastewater treatment) of metal ferrites and their graphene-based composites.
