| 摘 要： | 本文用电化学方法研究了硫在DMSO溶剂中第一步氧化还原过程的机理, 发现这个过程不是一个简单的双电子过程, 提出了更为合理的EEC机理, 数字模拟也表明该机理是可能的, 并从2.5次微分谱上发现了S6(II)的氧化峰, 其峰电位为-0.29V(相对于银电极). 还计算了该体系的某些动力学参数值.

| Abstract: | The mechanism of the 1st step electroredn. of S in DMSO was studied by electrochem. methods. Experimental results showed that it is not a simple 2-electron process. A EEC mechanism, supported by results of digital simulation, was proposed. An oxidation peak of S62- at -0.29 V was found on a 2.5 times differentiated linear scan voltammogram. Some kinetic parameters were calculated |
