帮忙解决一下电分析化学中的问题

The diffusion coefficient, Do, estimated from the slope of the Ip versus ν1/2 plot, is 7.7 × 10-7 cm2 s-1. This value is similar to those reported with other promoters and electrodes [3–10]. The separation of anodic and cathodic peaks at a low scan rate (20 mV s -1) is about 68 mV, which is consistent with a quasi-reversible one-electron transfer reaction. A further increase in the scan rate resulted in a larger separation of peaks. For example, a separation of ca. 94 mV occurs at 100 mV s- 1. Using Nicholson's method, the heterogeneous electron transfer rate constant ks of Cyt c at a PA/GCE was evaluated to be ca. 6.6 x 10 -3 cm s-1, which is about seven times the value reported in the literature [12]. Therefore all the above characteristics suggest that PA adsorbed on the electrode surface can act as an effective promoter for the redox reaction of Cyt c. 上面是一偏文献中的一部分，请问一下 这个扩散系数D以及 the heterogeneous electron transfer rate constant ks 是怎么求出来的，还有 Nicholson's method有相关的文献吗 谢谢 |

扩散系数求取用Randles-Sevcik equation， 以峰电流对扫速的平方根作图，得一直线，根据直线斜率求取。 文件名: heterogeneous electron transfer rate constant .pdf 描述: heterogeneous electron transfer rate constant .pdf 下载链接: http://www.fs2you.com/files/75c0c4a6-0118-11dd-82cb-0014221f4662/ 文件名: D0.pdf 描述: D0.pdf 下载链接: http://www.fs2you.com/files/75c203d7-0118-11dd-848c-0014221f4662/ |
