  • Preparation method and application for a resin-based iron oxide-containing composite phosphate removal adsorbent
    Patent number: 11529609
    Abstract: A preparation method of a resin-based iron oxide-containing composite phosphate removal adsorbent is provided. An alkaline anion resin is taken as a base, a potassium ferrate is used as an iron source, and a characteristics of ferrate ions easily adsorbed on a surface of the anion resin are utilized to prepare resin-based iron oxide-containing composite phosphate removal adsorbent by one-step in-situ hydrolysis precipitation, compared with the related art, a preparation process of the disclosure is relatively simpler, a time period is shorter, and a production cost is lower. It has a strong ability to eliminate interference from other anions in the waste effluents, and it has a strong adsorption capacity, fast adsorption speed and large adsorption capacity for the phosphate. Moreover, it has the advantages of strong regeneration ability and multiple repeated use times.
