A process for removing Hg2+ ions 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 form An+ wM3+ xMn1-xO2 where A can be cations such as Na+ or Mg2+, M3+ can be metals such as Fe3+ or Co3+, 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 Hg2+ ions from aqueous streams even in the presence of Mg2+ and Ca2+ ions. |
