摘要：
Ammonium ions are selectively removed from an aqueous stream by contacing the stream at adsorption conditions with a new family of crystalline molecular sieves having a microporous structure of ZrO 3 octahedral units, and at least one of SiO 2 tetrahedral units and GeO 2 tetrahedral units which can, optionally, contain M metals such as titanium, niobium, or tin. These novel molecular sieves adsorbents are prepared hydrothermally from a reaction mixture composed of reactive sources of the components.
