The feasibility of synthesizing zeolite by hydrothermal method,usingthe blast furnace slag as raw material was studied. The synthesis product was characterized by means of XRD,FTIR,SEM,TEM and BET. The zeolite made from blast furnace slag was A-type zeolite ,and the specific surface area of zeolite particle was more than 150m2/g,and its average pore size was about 1nm.The zeolite derived from blast furnace slag was used as a low cost adsorbent for ammonia removal from aqueous solution. We explored the influence of pH, initial ammonia concentration,the dosage of zeolite and the adsorption time on the adsorption kinetics. As the results of the batch adsorption experiment showed, the optimal dosage of the zeolite was 2g/L ,and the adsorption equilibrium could be reached in 30 min, and the highest removal rate could be over 90% .The adsorption kinetic was fit in pseudo-second order kinetic model.
