Abstract
A process for removing Hgions from a liquid stream is disclosed. The process involves contacting the liquid stream with specified ion-exchangers based on manganese oxides and metallomanganese oxides of the formAMMnOwhere A can be cations such as Naor Mg, Mcan be metals such as Feor Co, and the TIC, the theoretical ion exchange capacity per framework metal atom, varies from 0.08 to 0.25. These ion-exchangers are particularly effective in removing Hgions from aqueous streams even in the presence of Mgand Caions.
