| Abstract: | The preparation of activated carbon containing basic surface radical with oxidant and at under high temperature is introduced. The ion exchange capacity of modified activated carbon are determined. The effects of chemical factors such as pH and concentration of hexavalent chromium are investigated. The removal mechanism of hexavalent chromium by modified activated carbon is discussed. |
