摘要：This study was carried out to develop the low priced adsorbent by synthesizing the zeolite of high cation exchange capacity with the natural zeolite and to examine the adsorbing ability of this zeolite. The dominant clay minerals were clinoptilolite and mordenite in natural zeolite, while phillipsite in the synthesized zeolite. Adsorption reaction of NH,+ on zeolite was reached equilibtium after 2 hrs. The amount of adsorption was increased with increasing the concentration of NH,* or the pH of suspension. The cation exchange capacity of zeolite was slightly decreased below pH 4.0 by acidic treatment. It was estimated that the ability of the synthesized zeolite to remove noxious ions was better than that of the natural zeolite.
