摘要
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。
The photometric characteristics of Zr(Ⅳ)with 2-(3, 5-dibromo-2-pyridylazo)-5-diethyla-minophenol and fluoride in the presence of Triton X-100 have been studied. The maximum absorption and the apparent molar absorptivity of complex were found. The molar ratio of complex was determined. The reason of the sensitized effect has been discussed by molecular rbital theory.
