摘要： 运用单纯形优化的基本原理,用2种方法对铜(I)-新铜试剂-甲基橙三元配合物的组成进行了测定,所得组成比一致.在氯仿中该配合物的最大吸收波长为420nm,其配合比为1:2:1.组成为[Cu(Dphen)2]+MO-.2种方法均简便,准确,各具特色.

Abstract: Simplex optimization principles were applied to determining the composition of ternary complex of Cu(I)-Dphen-MO by two methods.Cu(I) reacts with neocuproine(2,9-dimethyl-1,10-phenanthroline) and methyl orange (MO) to form a colour ternary complex which could be extracted into CHCl3 and showed an absorption maximum at 420 nm.The molar ratio of the components of Cu(I):Dphen:MO in the complex was estimated to be 1:2:1,the composition is [Cu(Dphen)2]+MO-.It is shown that the two methods are simple and accuracy.
