Abstract: The interaction of RE ions(Ⅲ) with bovine serum albumin(BSA) has been stud-ied by UV spectrometry.It was found that the absorption of BSA at near 280 nm was en-hanced by RE ions.Ultraviolet spectra showed that the coordination atoms of BSA to REions are oxygen atoms, RE ions were coordinated with carboxyl groups of amino acids andcarbonyl groups of the peptide bonds on the out-shell of BSA.

Key words: rare earth ion, bovine serum albumin, UV spectrometry
