Abstract

The present invention discloses a polymeric lanthanum nanocomposite, and a preparation method and application thereof and relates to the field of environmental functional materials. The preparation method includes the following steps: (1) mixing lanthanum chloride heptahydrate with concentrated hydrochloric acid and dissolving the mixture in alcohol, adding a resin polymer, and stirring at room temperature; (2) draining the resin after the stirring for use; (3) adding the resin to a precipitant solution, and stirring at room temperature and then filtering out the resin; and (4) washing the resin with water until the resin is neutral, adding a NaCl solution, stirring and then filtering out the resin, and drying to obtain the polymeric lanthanum nanocomposite. The prepared polymeric lanthanum nanocomposites have a relatively more uniform distribution, and show a higher phosphorus adsorption rate.
