Preparation of room temperature ferromagnetic BiFeO3 and its application as an highly efficient magnetic separable adsorbent for removal of Rhodamine B from aqueous solution

▸ The adsorption removal application of room temperature ferromagnetic BiFeO3 ceramics has been investigated. ▸ The adsorption capacity of RhB on BiFeO3 can be reached to as high as 11.9 mg g−1 at RT (pH = 4). ▸ The carboxyl groups of RhB molecules are more likely to be adsorbed onto the positive charged surface of BiFeO3.
