20100181258 | THE FERRIC AND MANGANESE BINARY OXIDE BASED ADSORBENT, AND THE METHODS FOR THE PREPARATION AND APPLICAITON OF THE ADSORBENT - The present invention relates to a ferric and manganese binary oxide (FMBO) based adsorbent, its preparation and application method. The FMBO based adsorbent comprises a ferric and manganese binary oxide (FMBO) and a carrier. The mass ratio of FMBO to the carrier is between 0.2:100 and 15:100. The FMBO based adsorbent effectively removes the arsenic in groundwater, particularly the arsenite. The present invention also provides the equipment for preparation and application of the adsorbent. | 07-22-2010 |
