Tóm tắt

 In this study, a lanthanum-loaded biochar-based alginate hydrogel (La@SA@BC) was successfully fabricated at an optimal 1:1 mass ratio of lanthanum-loaded biochar to sodium alginate. A maximum phosphate (P) adsorption capacity of 56.5 mg/g was achieved under an adsorbent dosage of 0.9 g/L. The hydrogel demonstrated 90 % P removal efficiency at a pH of 3 and showed minimal adsorption reduction (<
 10 %) in the presence of competing ions (Cl
