Hi, Kulchaya. I assume this is a scholastic project. Ion exchange has been used for removal of hexavalent chromium in groundwater. Depending on the concentration of cadmium you might want to try chemical precipitation before the ion exchange. Both of these materials are toxic and must be reduced to the ppb range.
