Abstract The changes in surface hydroxyl structures and their absorption peaks after the adsorption of Cu²⁺ on the hematite and bayerite were studied by FTIR spectroscopy under the different pH values and Cu²⁺ concentrations. The result indicated that: (1) with the increase of Cu²⁺ concentrations, the H—O—H and OH deformation vibration of the hematite participated in the adsorption and Cu²⁺ combined with the Fe—O structure strongly, then Fe—O—(Cu) had been formed on the hematite surface. (2) In acid conditions, H⁺ in the solution destroyed the O—H structure of hematite surface and the existence of NO^-₃ prompted the production of a new peak (1 131 cm^-1). With pH value increasing, the hydroxy structure of hematite surface changed gradually from stretching vibration to deformation vibration, then the structures of Fe—OH and Fe³⁺—O^2- constantly changed. (3) The adsorption of Cu²⁺ on the bayerite happened in the high wave position. With the Cu²⁺ concentration increasing, the free OH bending vibration, the OH^- stretching vibration and its H—O—H bending vibration were all involved in the adsorption, and at the same time, Al³⁺ of Al—O was gradually replaced by Cu²⁺, which enhanced the vibration intensity of the low waves position. (4) With the increase in pH, the Al—OH bending vibration and Al—O stretching vibration changed gradually, which indicated that AlOCu⁺ and AlOCuOH structure had been formed on the bayerite surface after the adsorption.
