The adsorption on magnetic hybrid Fe3O4/HKUST-1/GO of methylene blue from water solution

Abstract

The adsorption processes of methylene blue from aqueous solution on Fe₃O₄/HKUST-1 and Fe₃O₄/HKUST-1/GO composites were compared. The addition of GO has greatly decreased the surface area and pore volume, led to smaller pore size, and enhanced the adsorption capacity of Fe₃O₄/HKUST-1/GO. The different interesting phenomena and the effect of GO were analyzed. The high adsorption capacity, excellent reusability and stability make Fe₃O₄/HKUST-1/GO attractive for the removal of MB from aqueous solution.
