摘要	MgO nanomaterials with different microstructure morphologies such as nanorods (MgOR), flower- like(MgOF), and lamellar (MgOL) were prepared for the adsorption performance in the removal of methyl orange. MgOR sample exhibited better adsorption ability in comparison to MgOF and MgOL sample due to its higher specific surface area, larger pore volume, and more available active sites. Langmuir isotherm model described well with the adsorption isotherm of MgO samples for the removal of methyl orange, and the pseudo-second-order adsorption model fitted well with the adsorption process of dye removal. The intra-particle diffusion model demonstrated that the adsorption process of different MgO samples was the combination of immediate surface diffusion and slow pore diffusion, in which the rate-determining step was the boundary layer diffusion.
