| 摘 要： | 将阳离子氢-四氮杂卟啉在碳电极表面吸附修饰后,浸入由CH3COOH,H3BO3和H3PO4组成并用0.2 mol/LNaOH溶液调节其pH值为2~12的缓冲溶液中,测得了其循环伏安图并得到了电势-pH图.根据电势-pH图中斜率的变化和氢-四氮杂卟啉的化学结构,得出在电势-pH图中各区域可能形成化合物的型态.

| Abstract: | After adsorbed on the surface of the graphite electrode,the cationic metal-free porphyrazine is immersed in the buffer solution consisting of CH_3COOH,H_3BO_3 and H_3PO_4,which pH value is adjusted to 2~12 by 0.2 mol/L NaOH.By measuring the cyclic voltammograms,the potential-pH diagram in pH=2~12 buffers is obtained.According to the slope changes of the diagram and the compound structure,the possible forming of the compound can be got in various areas of the diagram. |
