Activated carbon was employed as the adsorption carrier for the metal ions in HCl solution ofred mud, a solid waste produced in alumina industry. To improve the adsorption capacity to valuablemetal ions, the activated carbon was modified by chemicals including HNO3, H2O2, H2SO4, H3PO4, NH3,Na2CO3, and tri-butyl phosphate (TBP). It was found that the modifications contributed the highadsorption capacity to almost all metal ions we focused on. In the case of TBP, remarkably higheradsorption capacity and selectivity of Sc3+ was observed. The correlation between the surface areas, IRspectra of those chemically modified activated carbons and adsorption was schemed
