Abstract: A new method to improve the adsorption ability of expanded graphite (EG) was introduced in this paper. EG was modified by nano magnesium hydroxide. Modified expanded graphite (MEG) was characterized by SEM, XRD and FTIR. Then, the removal rate of Pb (Ⅱ) rose to 99% from 60.51% on MEG, and the removal rate of Cr (Ⅵ) could reach at 23.9% from 12.36%.
