Zusammenfassung:The synthesis of modified zeolite is based on natural zeolite as it's main raw material, mixed with certain amount of aluminum hydroxide, potassium muriate, sodium hydroxide and water, crystalized and colloidized under certain temperature and time period. This mvention is easy in synthesis method and low in cost. The products made from this invention can be used for extracting potassium from solution, especially from sea-water directly or for removing ammonium from waste water. It also can be used to adsorb caesium, rubidium, strontium etc. The dynamic capacity of potassium adsorption can reach 37 mg/g.dry, and for ammonium, 36mg/g.dry.
