英文摘要	Ceramsite materials made from coal ash and modifiers such as sawdust, clinoptilolite, clay, and CaCO(3) were prepared by pelletizing and high-temperature sintering to improve the adsorption to nitrogen and phosphorus. To incorporate Fe/C and Fe/Fe(3)C microelectrochemical cells, materials were also modified by the addition of metallic iron during the preparation process. Addition of more iron increased the Brunauer, Emmett, and Teller surface area and average pore diameter while decreasing the packing density and acid and alkali solubility. Examination using X-ray diffraction and X-ray fluorescence revealed that metallic iron modification also increased the abundance of Fe(3)C and FeC(8) particles and electrochemical effects. Time required to reach adsorption equilibrium decreased with addition of iron. Ammonia nitrogen and phosphorus adsorption isotherms and kinetics for each ceramsite composition followed the Langmuir isotherm model in a similar second-order manner with respect to the amount of iron. Results provide useful information for preparing ceramsites with enhanced nitrogen and phosphorus adsorption capacity and thus improved biofilter efficiency.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000282644300007&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Environmental; Environmental Sciences; SCI(E); EI; 10; ARTICLE; 10; 871-878; 27
