阳极溶出伏安法怎么做?欲仿照一篇文献用阳极伏安法 测试 汞离子 。文献如下:Fig. 4 compares square wave anodic stripping voltammetric??(SWASV) response for Hg2+ obtained at Au electrodes modi?ed withgraphene oxide (black curve) and with cysteamine-functionalizedgraphene (red curve). In this case, both electrodes were ?rst immersedinto aqueous solution of Hg2+ with the same concentration for 2 h, taken out of the solution, and rinsed with water. The electrodes werethen immersed into 0.10 M HCl solution containing no Hg2+ and were polarized at -0.10 V for 10 s before square wave voltammetric measurements. In an independent experiment, we found that the reduction at -0.10 V for 10 s was enough to reduce Hg2+??tethered onto the cysteamine-functionalized graphene surface.请问:1.在汞离子溶液中吸附了2h后,在0.1M的HCl中在-0.1V极化10s的目的是什么,为什么不直接测啊?2.谁用过CHI740D 电化学工作站 ?怎么设置这些条件呢?我只找到了square wave voltammetric 的选项,在system里有这些选项:Init E(V)? ?? ?,Final E(V)? ?? ?,Incr E(V)? ?? ?,Amplitude(V)? ???,Frequency(Hz)? ?? ?,Quiet time(Sec)? ?? ?,Senstivity(A/V).在control菜单中找到Stripping mode选项,见下图。本人对电化学所知甚少,求电化学高人指点,解释得越详细越好!文献Stripping Mode查看更多7个回答 . 26人已关注
