摘　　要：A new method of zeroing anisotropy spectrofluorometry has been developed.When a mixture of two components is determined by anisotropy spectrofluorimetric method,and the excitation wavelength is selected at the intersection points of the apparent excitation spectra corresponding to Ⅱ and In for the component A,then its anisotropy values are zero,and the measured anisotropy values can thus be used for the determination of the component B & vice versa.This method had been used for the simultaneous determination of a binary mixture of rhodamine B and pyronine G,and the determination of rhodamine B in a ternary mixture of rhodamine 6G,rhodamine S and rhodamine B using the common intersection points of and Ⅰ_(?)excitation spectra of rhodamine 6G and rhodamine S as the excitation wavelength.The results are quite satisfactory.A new method of zeroing anisotropy spectrofluorometry has been developed.When a mixture of two components is determined by anisotropy spectrofluorimetric method,and the excitation wavelength is selected at the intersection points of the apparent excitation spectra corresponding to Ⅱ and In for the component A,then its anisotropy values are zero,and the measured anisotropy values can thus be used for the determination of the component B & vice versa.This method had been used for the simultaneous determination of a binary mixture of rhodamine B and pyronine G,and the determination of rhodamine B in a ternary mixture of rhodamine 6G,rhodamine S and rhodamine B using the common intersection points of and Ⅰ_(?)excitation spectra of rhodamine 6G and rhodamine S as the excitation wavelength.The results are quite satisfactory.
