摘　　要：The effect of Tb3+ ion on the Activity Index (RZ=A403/A275) of HRP was investigated by a combination of ultraviolet-visible, FT-infrared and X-ray photoelectron spectroscopic techniques. It was found that Tb3+ ion could bond to the O and/or N group of the amides in the polypeptide chains of HRP, leading to a decrease in the enzymatic activity index of HRP.The effect of Tb3+ ion on the Activity Index (RZ=A403/A275) of HRP was investigated by a combination of ultraviolet-visible, FT-infrared and X-ray photoelectron spectroscopic techniques.
