Removal of Arsenic and Selenium with Rehydrated Clay Minerals

Popis výsledku v původním jazyce

Arsenic and selenium are of an increasing environmental attention due to their significance to human health. The use of clay materials as selective sorbents of different contaminants belongs to very efficient methods. A natural kaolinite was calcined tometakaolinite and than rehydrated at different temperatures to a highly porous sorbent. The specific surface and pore distribution of new phases were assigned. In addition, the obtained kaolin was also pre-treated with Fe3+ ions to improve its sorption affinity to anionic particles. Fe-modified kaolin was then used for the adsorption of As/Se oxyanions, and the adsorption efficiency in dependence on the physical chemical properties (pH, As/Se concentration) of initial solution and the surface propertiesof sorbent (specific surface, modification method) were investigated. The adsorption properties of newly prepared sorbents were finally compared with calcined kaolins in both raw and modified forms. The maximum adsorption capacities of r
