PROCESS FOR REMOVAL OF SELENIUM FROM WATER BY DITHIONITE IONS |
| 摘要 |
A method for efficiently removal of oxidised selenium from liquid, such as FGD wastewater. The method involves adding a non-iron- based reducing agent (e.g. sodium dithionite) and preferably Fe(II) ions to the liquid at a pH of above 7.5 or 8 and precipitating elemental selenium from the liquid. |
