【摘要】 利用单扫示波极谱法研究了邻苯三酚的自氧化机理，依据多种电化学参数和紫外可见吸收光谱对主要极谱峰和吸收峰的变化规律作出合理解释，指出邻苯三酚自氧化过程中存在多种电子转移历程，单扫示波极谱法可直接监测半醌和醌等中间和最终产物的变化。更多还原

【Abstract】 The auto-oxidation mechanism of pyrogallol was studied by single-sweep oscil- lopolarography. Depending on electrochemical parameters and UV-Vis spectra, behaviours of primary peaks in polarogram and UV-Vis spectra were demonstrated. There. are multi- electronic transfer courses in the auto-oxidation of pyrogallol. Intermediate and final prod- ucts of reactions,for example, semiquinones, quinones et al. can be detected by single- sweep oscillopolarography.更多还原
