卟啉的分子截面积大,与一些金属离子配合都具有很高的摩尔吸光值,已被称之为“超高灵敏度的显色剂”。文献研究了在阳离子表面活性剂存在下,锰与阴离子卟啉的增敏反应,本文在阴离子表面活性剂存在下,采用导数光度法,探讨的锰与阳离子卟啉的增敏作用。试验表明,试液中无论是单体还是胶束对锰与阳离子卟啉生成的Mn-T(4-TAP)P二元配合物均有增敏作用,最大吸收波长紫移。 Porphyrins molecular cross-sectional area, with some metal ions have a high molar absorptivity, has been called “ultra-high sensitivity of the developer.” In the literature, the sensitization reaction between manganese and anionic porphyrin was studied in the presence of cationic surfactant. In this paper, the sensitization of manganese and cationic porphyrin was discussed using derivative photometry in the presence of anionic surfactant. Experiments show that both the monomer and the micelle of the test solution have the sensitizing effect on Mn-T (4-TAP) P binary complex formed by manganese and cationic porphyrin, and the maximum absorption wavelength shifts purplely.
