Lanthanum-modified sepiolite for real application of phosphate removal from rural sewage.

Being able to cause eutrophication, a severe ecological problem that leads to the demise of aquatic animals, excessive phosphate in water bodies, has been a threat to the environment. Aiming to remove phosphate from wastewater in rural areas, adsorption is a promising method. In this study, a novel phosphate adsorbent, SEP-La, was synthesized by doping lanthanum into sepiolite.
