Mesoporous composite material, and preparation method and application thereof
Rare earth phosphate compounds are generated by reacting rare earth metal salts with mesoporous materials and phosphate source solutions to form mesoporous composite materials. This solves the problems of complex preparation and low adsorption capacity of lead adsorption materials in the existing technology, and achieves efficient and selective adsorption of lead, which is suitable for lead-containing wastewater treatment.
