| 摘 要： | 使用实验室自制高效光降解反应器研究了隐性孔雀石绿(LMG)在有机相中的光化学降解过程,探讨了反应介质、盐度对LMG光化学降解反应动力学的影响.实验结果表明,LMG在有机相中的光化学降解反应为近似一级反应;反应介质的极性对LMG光化学降解反应影响显著,介质极性越大,反应速率越小;盐度对LMG光化学降解反应无明显影响.LMG在光照条件下生成孔雀石绿(MG),随后失去一个或多个亚甲基,生成一系列去甲基化衍生物.

| Abstract: | The mechanism of photochemical degradation of leucomalachite green(LMG) in solvent media has been investigated with a laboratory-built photochemical degradation(PCD) device.Spectrometric characteristics of LMG and it main degradation products suggested that LMG had deassociated under UV irradiation.The kinetics of the photochemical reaction demonstrated that laboratory-built PCD was of high efficiency for off-line degradation of interested organic compound.The photo-degradation reaction of LMG in organic so... |
