摘要： 近年来,对于大环卟啉化合物在分析化学中的应用研究得越来越广泛。鉴于非水溶性卟啉较水溶性卟啉易于合成和提纯,我们研究了meso-四-(3-甲基苯)卟啉[T(3-MP)P]与镉的反应。结果表明,T(3-MP)P与镉的显色反应有较高的灵敏度(ε=3.8×105),是测定镉的灵敏方法之一。

Abstract: Properties of mcso-(3-mcthylphenyl) porphyrin and its complex formation reaction with cadmium (Ⅱ) were studied. The dissociation constant of the reagent was calculated by PC-8001 Bcomputer according to A～pHcurve, pK3.4 = 5.67 ± 0.07. The complex has an absorption maximum at 432nm, and the maximum absorbancc was obtained in the pH 9.2 to 10.0. The apparent molar absorptivity of the complex is 3.8×105.
