The Saudi Arabian white silica is used as a starting material for preparation of adsorbent for heavy metals and some organic dyes. Hydrothermal treatment of white silica with aluminum source resulted in an amorphous phase of microporous materials with large enhancement of ion exchange properties in addition to adsorption of some organic dyes. In this research we examine the modified white silica towards ion exchange of Cu 2+ , Co 2+ , and Ni 2+ ions. The ion exchange curve was elucidated. Cu 2+ has higher affinity for ion exchange while Co 2+ and Ni 2+ nearly the same affinity. Adsorption of methylene blue and methyl red was examined and a simulation study was performed.
