The 3-aminophthalic acid anion is a light emitter in luminol chemiluminescence. In the present study, the chemiluminescence of the 3-aminophthalic acid anion itself in the presence of hydrogen peroxide-cobalt (II) was studied. The results indicated that 3-aminophthalic acid anion is highly chemiluminescent in the typical hydrogen peroxide-cobalt (II) system. The peak wavelength of this chemiluminescence and the kinetic profile of the 3-aminophthalic acid anion-hydrogen peroxide-cobalt (II) reaction showed similarity with that of luminol, but the chemiluminescence of 3-aminophthalic acid anion had a much lower background signal. In addition, the chemiluminescence mechanism of 3-aminophthalic acid anion-hydrogen peroxide-cobalt (II) was also discussed and speculated as the interaction between 3-aminophthalic acid anion and singlet oxygen.

3-氨基邻苯二甲酸阴离子-过氧化氢-钴（II）的化学发光。

3-氨基邻苯二甲酸阴离子是鲁米诺化学发光中的发光体。在本研究中，研究了在过氧化氢-钴（II）存在下3-氨基邻苯二甲酸阴离子本身的化学发光。结果表明，3-氨基邻苯二甲酸阴离子在典型的过氧化氢-钴（II）体系中具有高度化学发光性。该化学发光的峰值波长和3-氨基邻苯二甲酸阴离子-过氧化氢-钴（II）反应的动力学曲线显示出与鲁米诺的相似性，但是3-氨基邻苯二甲酸阴离子的化学发光具有低得多的背景信号。此外，还讨论了3-氨基邻苯二甲酸阴离子-过氧化氢-钴（II）的化学发光机理，并推测是3-氨基邻苯二甲酸阴离子与单线态氧之间的相互作用。
