| 摘 要： | 利用吸收光谱法和直流极谱法研究了Cu~(2+)的还原状态、抗坏态、抗坏血酸浓度及溶解氧对Cu~(2+)与三磺基四苯基卟啉配位反应的影响。结果表明Cu~(2+)与三磺基四苯(?)基四苯基卟啉配位反应的可能机制为抗坏血酸首先将高价铜还原为亚铜,亚铜离子与配位剂生成对氧成对氧敏感的不稳定中间体Cu~(Ⅰ)——三磺基四:苯基卟啉配合物,立即又被溶解氧氧化为Cu(Ⅱ)——Ⅱ)——三磺基四苯基卟啉配合物。

| Abstract: | The effects of reductive Cu2+.ascorbic acid concentration and solution oxygen on the com-plexation reaction of Cu2+with 3-sulfo-group-4 benz-porphyrin is studied by absorption spectrum and direct current polarogram.It is shown that the possible mechanism is the complex compound of Cu+ will be oxidized by solution oxygen when Cu2+is reduced by ascorbic acid. |
