Abstract

A magnetic composite consisting of iron oxide and a cobalt-aluminum layered double hydroxide, Fe₂O₃@Co-Al LDH was prepared through linking of Fe₂O₃ to Co-Al LDH by sodium acetate. Layered double hydroxides are generally described as [M²⁺_1–xM³⁺_x(OH)₂][A_n–x/n·mH₂O], where M²⁺ and M³⁺ are divalent and trivalent metal cations, respectively, and A is an n-valent interlayer guest anion. The composite was characterized by XRD, FTIR and UV-Vis. spectroscopy methods. Afterwards, the composite was used for methyl-orange adsorption in aqueous solution. The UV-Vis spectrum indicates that the adsorption process was satisfying. In effect, after several washings of the composite, no decrease of the adsorption capacity was observed.
