The sorption performance was better under acidic conditions due to enhanced electrostatic attraction. Humic acid (HA) and PO43- inhibited the sorption through competing for sorption sites, while Fe3+ promoted sorption due to formation of additional FeOAs complexes on sorbent surface. The experimental observations, spectroscopic insights, and density functional theory (DFT) calculations consistently indicate that the sorption of aromatic organoarsenicals on the flower-like CoFe2O4 particles occurs mainly throu
