详细地研究了铝-络天青S-锌-8羟基喹啉配合物的形成条件及有关反应过程。配合物的最大吸收峰位于548nm,摩尔吸光系数ε_(548)=6.4×10~4。配合物中各组分的摩尔比Al:CAS:Zn:HOx=2:6:3:3,相应的分子式为[Al(CAS)_3]_2[ZnHOx]_3。反应曾用于稀土样品中铝的测定,取得了比较满意的结果。
The formation conditions of aluminum-cypermethrin-zinc-8-hydroxyquinoline complex and related reaction processes were studied in detail. The maximum absorption peak of the complex was at 548 nm, and the molar absorptivity ε 548 was 6.4 × 10 ~ 4. The molar ratio of the components in the complex is Al: CAS: Zn: HOx = 2: 6: 3: 3, and the corresponding formula is [Al (CAS) _3] _2 [ZnHOx] _3. The reaction has been used for the determination of aluminum in rare earth samples and satisfactory results have been obtained.
