本文系统研究了在非离子表面活性剂Triton X-100存在下Zr与5-Br-PADAP及F离子形成多元配合物的条件,测定了配合物的最大吸收波长和表观摩尔吸光系数,确定了配合物的组成,并用分子轨道理论论述了光谱跃迁时强度突跃的原因,较好地解释了实验现象。
In this paper, the conditions for the formation of multiple complexes of Zr with 5-Br-PADAP and F ions in the presence of non-ionic surfactant Triton X-100 were studied systematically. The maximum absorption wavelength and apparent molar absorptivity of the complex were determined. The composition of the complexes was discussed. The reason of sudden jump in intensity transition was discussed with molecular orbital theory, and the experimental phenomena were well explained.
