Abstract

AbstractSorption 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 demonstrated that siderite reduces selenite ions in solution, showing a higher selenium immobilization capacity compared to other iron(III) minerals, which is probably due to both sorption and reduction processes.
