Abstract


The natural zeolite powder has been used as the primary raw material to make a sort of porous ceramic foam, which is of reticular structure with millimeter-scaled pores. After desilicating this foam, an Al-Fe type Prussian blue analogue (PBA) with a strong function of ion exchange was loaded on the ceramic surface by directly yielding. The resultant PBA-loaded porous samples were examined to adsorb the harmful species in water, and the adsorption efficiencies were investigated for some typical harmful ions, i.e., Cd2+, Cs+ and As (V). A good adsorption performance was found for the PBA-loaded porous samples.
