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 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.

Se(IV) 固定在天然菱铁矿上：对高放核废料储存库的影响

研究了金属和半金属在菱铁矿上的吸附过程，因为它具有从天然水中去除污染物的潜力，其广泛的可用性，以及它降低某些污染物（如硒）氧化态的能力。在这项工作中，已经证明菱铁矿减少了溶液中的亚硒酸盐离子，与其他铁 (III) 矿物相比，显示出更高的硒固定能力，这可能是由于吸附和还原过程。
