摘　　要：合成了一种新的水溶性磺化四－（４－三甲胺苯基）卟啉镉配合物。用元素分析、红外光谱和紫外可见光谱表征了配合物的组成与结构。用改进的三波长Ｓａｎｃｈｅｚ法测得了该配合物在ｐＨ＝１３．０，μ＝０．２和２５℃条件下的稳定常数Ｋ＝６．０５×１０＾７，组成比为１：１。Cadmium ( Ⅱ) tetra-(p-trimetheylammoniurnphenyl) porphyrin iodide coordination compoud, C56H72N8O6I4Cd (CdTAPPI · 6H2O), was prepared and characterized by UV absorption spectra, IR spectrometry and elemental analysis. The stability constant of CdTAPPI ·6H2O was determinated by three-wavelength spectrophotometry at pH=13. 0, μ=0. 2(NaNO3) and t = 25℃ , with the result K= 6. 05 × 107.
