Abstract	Hierarchical core–shell Fe3O4@Mg3Al–CO3 layered double hydroxide (LDH) as an efficient magnetic adsorbent was prepared and investigated for the adsorption of anionic dye under ambient conditions. The material was thoroughly characterized by a variety of spectroscopic methods, which indicate that it was composed of spherical Fe3O4 (ca. 330 nm) core with a vertically aligned Mg3Al-CO3 layered double hydroxide shell coating. Calcination of Fe3O4@Mg3Al–CO3 LDH at 400 °C gives a layered double oxide coated Fe3O4 nanoparticles (Fe3O4@Mg3Al–CO3 CLDH), which is shown to be an efficient magnetic adsorbent for removal of the anionic dye, C.I. Acid Yellow 219 (AY219) from aqueous solution under ambient conditions. The adsorption of AY219 from aqueous
