Abstract | The removal of cadmium(II) from two synthetic cadmium plating wastewaters by an activated carbon adsorption process has been investigated. Among the 17 different types of activated carbon tested, it was found that the acidic activated carbons, namely Nuchar SA and Nuchar SN exhibited the greatest Cd(II) removal capacity. Chemical regeneration with strong acid of the exhausted carbon was examined, along with thermal-chemical process. Two Cd(II) treatment schemes were proposed, together with an economic evaluation of each scheme. The cost of the activated carbon adsorption process was also compared with several treatment processes including insoluble sulfide precipitation, alkaline neutralization precipitation, and ion exchange process. |
