Preparation method and application of resin-based iron oxide-supported composite phosphorus removal adsorbent

The invention discloses a preparation method of a resin-based iron oxide-supported composite phosphorus removal adsorbent. The resin-based iron oxide-supported composite phosphorus removal adsorbent is prepared through one-step in-situ hydrolysis precipitation by taking strongly basic anion exchange resin a parent body and potassium ferrate as an iron source and using the characteristic that ferrate radical ions are extremely easily adsorbed on the surface of anion resin. Compared with an existing preparation method, the preparation method of the invention has the advantages of simple preparation process, short time period and low production cost. The adsorbent has the advantages of strong capacity of eliminating interference of other anions in wastewater, strong phosphorus adsorption capacity, high speed, large adsorption capacity, strong regeneration capacity, multiple reuse times and the like. 本发明公开了一种树脂基负载铁氧化物复合除磷吸附剂的制备方法，以强碱性阴离子交换树脂为母体，以高铁酸钾为铁源，利用高铁酸根离子极易吸附于阴离子树脂表面的特性，通过一步法原位水解沉淀制备树脂基负载铁氧化物复合除磷吸附剂，与现有制备方
