Abstract
A magnetic adsorbent, preparation method therefor and application thereof. The magnetic adsorbent is made by loading a weakly material with high adsorption capacity, an iron-based gel, onto a strongly magnetic ferrite material with low adsorption capacity by means of in-situ reaction. The magnetic adsorbent is used for removing heavy metal pollutants and phosphate pollutants from water.
