The ultraviolet absorption peak narrows, absorption intensity increases, the absorption margin becomes steep and moves to longer wavelength, the optical band gap decreases as well.
紫外吸收峰变窄，强度增加，吸收边变得陡峭并向长波方向移动，光学带隙降低。
Conclusion: the improvement method is suitable for the ultraviolet determination of two component mixture in which the interference component possess an undisturbed absorption peak.
结论：所提出的改进方法适用于干扰组分有单独吸收峰的双组分混合物的紫外测定。
The UV spectra indicated that the complexes' ultraviolet absorption is mainly the ligands' absorption, but the location of peak is drifted.
紫外光谱的研究表明，配合物的紫外吸收主要表现为配体的吸收，但是吸收峰的位置发生了移动；
