摘要

Spent FCC catalyst with lanthanum is proposed as a novel P-removal adsorbent.

The spent FCC catalyst exhibits 99% adsorption efficiency for low P-concentration wastewater (C₀<5.0 mg/L).

High affinity, endothermic reaction and fast sorption kinetics are achieved.

The phosphate is adsorbed in the form of LaPO₄ and KH₂PO₄.
