Herein, an innovative arginine-functionalized imprinted aerogel (AFIA-1:4) was fabricated by click chemistry and imprinting modification for overcoming this trade-off through synergistic weak interactions. Results shown that AFIA-1:4 exhibited high adsorption capacity (Qmax of 40.65 mg/g, 30.44 % higher than phoslock), rapid kinetics (15 min), and broad pH applicability (3-11) at 2 mg P/L solution. Moreover, its selectivity coefficient ranged from 10 to 90 even with 15- to 125-fold excess interfering anions, surpassing common adsorbents. After 10 cycles, AFIA-1:4 still maintained 98.15 % regeneration rate with 99.14 % phosphate desorption.

Results revealed that there are three extractable fractions of SMX in biochar-soil systems, allowing the migration of SMX among these various fractions. 1.0 % biochar could increase 8.5 %∼14.1 % BR fraction and 17.9 %∼36.9 % non-extractable fraction, respectively.
