The simultaneous sorption of cations and anions at the mineral-water interface can substantially alter their individual sorption characteristics; however; this phenomenon lacks a mechanistic understanding. Our study provides direct spectroscopic and modeling evidence of the molecular cosorption mechanisms of the cadmium ion (Cd2+) and phosphate (P) on goethite and layered manganese (Mn) oxide of birnessite; through in situ attenuated total reflection Fourier-transform infrared (ATR-FTIR); P K-edge X-ray absorption near-edge structure (XANES) spectroscopy; and surface complexation modeling. Phosphate synergistically cosorbed with Cd on goethite predominantly through P-bridged ternary complexes (≡Fe-P-Cd) and electrostatic interactions at wide pH conditions. Likewise; P and Cd exhibited synergistic cosorption on birnessite by forming P-bridged ternary complexes (≡Mn-P-Cd) and weak competitive sorption at the layer edge sites. As pH and Cd loading increased; the surface P species transitioned from a binary complex to a ternary complex and/or Cd3(PO4)2 precipitate for both goethite and birnessite. Compared to that in solution at pH 8; the formation of Cd3(PO4)2 was inhibited by the presence of goethite and birnessite; ascribed to the specific adsorption of P and Cd; more pronounced in birnessite due to the stronger sorption of Cd at its vacant sites. The discovered cosorption mechanisms of P and Cd have important implications for understanding and predicting their mobility and availability in Cd-contaminated settings. © 2024 American Chemical Society;
