摘要
基于β吸收带利用比耳定律和光谱实验研究了浓度大于１０－４ｍｏｌ·Ｌ－１的ＮｉＴＭＰｙＰ〔ｍｅｓｏ四（４Ｎ甲基吡啶基）卟啉合镍（Ⅱ）〕的溶液平衡性质．结果表明，在该溶液中ＮｉＴＭＰｙＰ以四配位ＮｉＴＭＰｙＰ和六配位ＮｉＴＭＰｙＰ（Ｈ２Ｏ）２的平衡混合物存在，丙酮和咪唑的加入以不同方式对该平衡产生影响．
The equilibrium properties of NiTMPyP〔nickel(Ⅱ)tetrakis(4Nmethylpyridyl)porphyrin〕above 10-4mol·L-1 in aqueous solutions were studied with experiments of Beer's law and spectra based on β absorption bands.The selfmade cell with a thickness of 0.1cm were used in experiments.The results showed that NiTMPyP exists in these solutions as an equilibrium mixture of fourcoordinate NiTMPyP and sixcoordinate NiTMPyP(H2O)2.Acetone and imidazole added exerted different influence on the equilibrium.
