摘要
用流通光度滴定法建立了测定多元络合物组成的快速方法。方法简单,仅用中心离子和配体各一个标准溶液。经测定几组络合物体系。实验结果与文献值完全一致。
A flow-through photometric titrimetric method is established for the determination of complex of composition. The method is simple and rapid using only a standard solution of the metal ion and ligand respectively. The ratio of Ti( Ⅳ) : chromotropic acid : diantipyrylmethane. V(Ⅴ) : 2(5-bromo-2-pyridyl)azo-5-di-ethylaminophenol : H2O2 and V( V ) : 4(2-pyridylazo)resorcin : H2O2 is 1:2:2,1:1:1 and 1 : 1 : 1, respectively. The results are in good agreement with the literature values.
