Se(IV) immobilization onto natural siderite: implications for high-level nuclear waste repositories

Sorption processes of metals and semimetals on siderite are studied because of its potential adequacy for removing contaminants from natural waters and its wide availability, as well as its capacity to reduce the oxidation state of some contaminants such as selenium. In this work, it has been demons...
